Intended use
The machine may only be deployed on surfaces that can support it. It is intended solely for deployment for compressing loose surfaces, road foundations, road surfaces, and similar compactible foundations. Any other deployment or a deployment beyond this is not deemed as intended. The manufacturer/supplier is not liable for any damage resulting from this. The user will bear the complete risk. The intended use also includes the observance of the operating instructions as well as the compliance with the inspection and maintenance requirements set out by the manufacturer. This machine has been built to the state-of-the-art standards and under generally accepted safety regulations. However, danger to life and health of the user or impairment of the machine and of other objects can arise during the use of the machine. This machine may only be used in technically unobjectionable condition, as well as according to the intended use, and aware of safety issues and possible dangers, always observing the operating instructions. All safety devices removed for transport purposes (anti-rollover device, ROPS, handles, silencers, etc.) must be reinstalled on the machine before use. In particular, any troubles that could have an effect on safety must be eliminated immediately. Arbitrary changes will exclude the manufacturer’s liability for any damage resulting from this.
Installation instructions for the safety device ROPS anti-rollover bar
The machine may only be operated with the installed anti-rollover device!
Selection and qualification of staff; general duties
- Any work with or on the machine must only be performed by appropriate and reliable staff. The minimum legal age must be observed.
- Only trained or instructed staff may be used.
- The responsibility of the staff for operation, maintenance, and servicing must be clearly defined.
- It must be ensured that the machine is only operated by staff ordered to do this.
- The responsibility of the machine operator
- concerning traffic regulations must also be defined; these must allow him or her to reject unsafe instructions of third parties.
- Any staff to be trained, instructed, taught, or any staff within a general education measure, may only work on the machine under the continuous supervision of an experienced person.
- Any work on electrical equipment of the machine may only be performed by a specialised electrician or by instructed persons under the supervision of a specialised electrician and according to the rules of electric engineering.
- Any work on suspensions, braking, and steering installations may only be performed by specialised staff trained for this.
- Only staff with specialist knowledge and experience of hydraulics may work on hydraulic installations.
Fuel
- Danger of explosion!
- Increased fire hazard!
- Danger of intoxication!
- Be careful during the handling of fuel! Prior to refilling fuel, the diesel engine and fuel-operated heating systems, if any,
must be shut down. Do not fill up fuel in closed rooms. Wipe away spilled fuel immediately. Do not breathe in vapours. Fuel is flammable and explosive. Thus, avoid open flames or igniting sparks during fuel handling, or even near fuel. Do not smoke! This also applies where the characteristic smell of fuel can be detected. In case of fuel smells in the machine itself, the cause must be detected and removed immediately.
Only operate the diesel engine with common diesel fuel with a sulphur content below 0.5 %. In case of a higher sulphur content, the engine oil change intervals must be shortened.
Admissible fuel specifications are:
- DIN EN 590
- JIS K 2204 Grade 1 and 2
- ASTM D 975-88: 1-D and 2-D
Marine Diesel Fuel, heating oils etc., may not be used. The stated engine oil change intervals require a diesel fuel with a maximum sulphur content of 0.5 % and a continuous ambient temperature of a minimum of -10 °C (14 °F). For diesel fuels with a fuel content between 0.5 % and 1.0 %, or continuous ambient temperatures below -10 °C (14 °F), the engine oil change intervals must be halved. If diesel fuels with manufacturer-guaranteed winter properties are used, additives can be omitted until the guaranteed temperature is reached. In case of low temperatures, fluidity and filterability of the diesel fuel are insufficient (crystallised paraffins). Therefore, diesel fuels with increased low-temperature properties are available in winter
months. Prior to the cold period, take care to fill up winter diesel fuel. In order to maintain fluidity and filterability for summer diesel fuel at low temperatures, a quantity of engine petroleum, depending on the external temperature (observe country-specific regulations), or commonly available fuel additives, so-called flow improvers, must be mixed into the vehicle tank. A dissolving of already crystallised paraffins is impossible.

Precaution measures prior to machine start
The machine may only be started and driven by specialist persons authorised to do so. Danger of accidents and danger of injuries! The operator must get familiar with the working environment at the place of utilisation prior to the start of work. The working environment includes, e.g., obstacles in the working and traffic area, the load carrying capacity of the underground, and necessary safeguarding towards public traffic. Make yourself familiar with all devices and operating elements of the machine and its functions. It is too late to do this during work. Ensure that nobody is in front of, under, or behind the machine. Do not allow anybody to stay in the danger zone of the machine. Ensure sufficient sight, and adjust necessary mirrors correctly. Keep operation and safety signs clean. Illegible or lost signs must be replaced immediately. After maintenance and repair work requiring a removal of the driver’s cabin/ROPS anti-rollover device, the driver’s cabin/ROPS anti-rollover device must be screwed again securely to the machine frame. This is the only way to ensure the rollover protection. After maintenance work, check that all tools have been removed from the machine and that all protection devices have been re-attached and are in the protection position. The diesel engine may only be started from the driver’s seat. The engine must not be started by short-circuiting the electric contacts at the starter.
MAINTENANCE
INTRODUCTION
General
This machine requires care and maintenance like any other technical device. The extent and the frequency of the maintenance work depend essentially on the operating and deployment conditions, which are very different in many cases. In case of more difficult operating conditions, the machine must have maintenance in shorter intervals than scheduled for normal operation. The maintenance intervals are determined according to the running time of the operation hours counter; for this, additional maintenance work has to be performed during the running-in time according to the running-in regulations. The work necessary for care and the conservation of the operational safety of the machine is listed in the following sections. The running in regulations, the maintenance intervals, and the care measures for the diesel engine can be found in the operating instructions of the engine manufacturer and must be observed. Specialist knowledge is necessary for the execution of some inspection and maintenance works; these cannot be given in the scope of these operating instructions. We recommend having these works performed by trained, specialised staff.
Notes on spare parts ordering
- In order to have your HAMM roller always optimally operative, we recommend that you keep the necessary maintenance parts listed in 3.2.2 always in stock.

Safety
- Danger of accidents and danger of injuries! Observe safety and accident prevention regulations.
Carry out maintenance work only when the engine is stopped. Only open the engine hood when the engine is at a standstill. Keep away from moving, rotating, or revolving parts; do not touch these (danger of accidents). Only perform an oil change when the engine is at operating temperature. Danger of burning or scalding. Perform maintenance work on the engine exclusively according to the operating instructions of the manufacturer. Any work in the danger area of the articulated frame steering may only be performed with the engine at a standstill and with the electric system switched off. Before the start of work, pull off the key from the battery disconnector (if existing). If a battery disconnector doesn’t exist, remove the earthing strap from the battery (danger of life). If the machine is equipped with a locking device for the articulated frame steering, it must be latched prior to start of work. The machine must stand on level ground for the control of liquid levels or for the change of liquids (fuel, oil, refrigerant, water). This is the only way to enable an exact determination of liquid quantities.
In order to protect electronic components as e.g. central control unit, monitor unit, sensors, relays, etc., all connectors must be pulled out before welding work; otherwise, the electronic components will be destroyed. The negative pole must be applied directly to the constructive part to be welded. Take care of a good contact!
- Only appropriate and clean lubricants may be used. Otherwise, the guarantee becomes void.
Use of biologic hydraulic oil
The hydraulic system of the machine is generally filled with mineral oil in the factory. All maintenance intervals given in these maintenance instructions are related to mineral oil. The use of biological hydraulic oil is admissible under the following circumstances:
- Only biological oil based on special synthetic saturated complex esters may be used. The products used and recommended by HAMM can be taken from the lubricant indications 3.2.2. Other oils used must correspond to the specifications of the oil mentioned above. The neutralisation value (oil acid) may not be bigger than 2.
- When the hydraulic oil is changed (biological oil replaces mineral oil or vice versa), all filters in the oil circuit must be changed after 50 operating hours. After that, the filter change intervals given in these instructions apply again.
- Used biological oil must be disposed at a reliable place of disposal, just like mineral oil.
Refrigerant conditioning
For liquid-cooled engines, special care must be taken for the conditioning and the control of the refrigerant; otherwise, corrosion, cavitation, and freezing can cause motor damage. The conditioning of the refrigerant is performed by adding a cooling system protection agent to the refrigerant. The cooling system requires constant monitoring. Apart from the control of the refrigerant level, this also implies the verification of the concentration of the cooling system protection agent. The concentration of the cooling system protection agent can be done with commercially available test devices (example: Gefo Glycomat ®). The concentration of the cooling system protection agent in the refrigerant should not exceed or fall short of the following values:
The products used and recommended by HAMM (free from nitrites, amines, and phosphates) can be taken from the lubricant indications 3.2.2. The factory-filled refrigerant mixture consists of 40 % cooling system protection agent and 60 % water. This guarantees freezing protection up to -25 °C (-13 °F). The cooling system protection agent can be purchased from the HAMM customer service, ordering o. 313238. The use of the cooling system protection agent offers effective protection against corrosion, cavitation, and freezing.

OPERATION MONITORING
(see also engine operating instructions)
Operation monitoring
When the electric system is switched on with the key switch (310), all illuminated indicators are activated for approx. 2 seconds for function control purposes. Check whether all illuminated indicators are operable. Observe the control and indication instruments from time to time. If an illuminated indicator indicates a failure, determine and remove the cause. You can find an exact description of the elements in the operating instructions, section 2.1.3.
Dry air filter
The operability of the air filter is monitored by an electric contamination indicator. Only if the illuminated indicator (203) flashes must the air filter cartridge be replaced (see maintenance once every 10 operating hours).
MAINTENANCE ONCE EVERY 10 OPERATING HOURS
Maintenance points at the engine for the engine oil change
The running-in regulations, the maintenance intervals, and the care measures for the diesel engine can be found in the operating instructions of the engine manufacturer and must be observed.
- A Oil filling spout
- B Oil dipstick
- C Oil drain screw
Check and clean the dry air filter
The operability control of the air filter cartridges must be performed prior to the start of work with the diesel engine running.
- Shortly, rev up the diesel engine to maximum speed. If the illuminated indicator (203) does not light up, both filter cartridges are still completely operable. If the illuminated indicator flashes, both air filter cartridges must be replaced. Observe the engine operation instructions! Replacement of air filter cartridges
- Open the clamps A at the air filter housing and remove the dust collector B in an upward direction.
- Check seals, replace if necessary.
