OVERVIEW
BEFORE YOU OPERATE, MAINTAIN OR IN ANY OTHER WAY, OPERATE THIS MACHINE:
READ and STUDY this manual. KNOW how to safely use the unit’s controls and what you must do for safe maintenance.
The machine has been built in accordance with state-of-the-art standards and the recognized safety rules. Nevertheless,
its use may constitute a risk to life and limb of the user or of third parties, or cause damage to the machine and to other
material property.
ALWAYS wear or use the proper safety items required for your personal protection.
For reasons of security, long hair must be tied back or otherwise secured, garments must be close fitting and no jewelry –
such as rings or watches - may be worn. Injury may result from being caught up in the machinery or from rings catching
on moving parts.
If you have ANY QUESTIONS about the safe use or maintenance of this unit, ASK YOUR SUPERVISOR OR CONTACT
ANY DISTRIBUTOR. NEVER GUESS - ALWAYS CHECK.
Never make any modifications, additions or conversions which might affect safety without the supplier’s approval. This
also applies to the installation and adjustment of safety devices and valves as well as to welding work on load-bearing
elements. Observe all fire-warning and fire-fighting procedures.
PRE-START INSPECTION
INSPECT your machine. Have any malfunctioning, broken or missing parts corrected or replaced before use.
Check the machine at least once per working shift for obvious damage and defects. Report any changes (incl. changes in
the machine’s working behavior) to the competent organization/person immediately. If necessary, stop the machine
immediately and lock it.
Take the necessary precautions to ensure that the machine is used only when in a safe and reliable state.
Operate the machine only if all protective and safety oriented devices, such as removable safety devices, emergency
shut-off equipment, sound-proofing elements and exhausts, are in place and fully functional.
The electrical equipment of machines is to be inspected and checked at regular intervals. Defects such as loose
connections or scorched cables must be rectified immediately.
VERIFY that all the instruction and safety labels are in place and readable. These are as important as any other
equipment on the compactor.
NEVER fill the fuel tank, with the engine running, while near an open flame, or while smoking. ALWAYS wipe up any
spilled fuel immediately.

SECTION 1 -
SAFETY PRECAUTIONS AND GUIDELINES
CHECK for WARNING tags placed on the machine. DO NOT operate the equipment until repairs have been made and
the WARNING tags have been removed by authorized personnel.
KNOW the location of the Emergency Shut-Down Control if the machine is so equipped.
OPERATING
In the event of safety-relevant modifications or changes in the behavior of the machine during operation, stop the
machine immediately and report the malfunction to the competent authority/person.
Always wear the prescribed ear protectors.
Always make sure that no person or obstruction is in your line of travel. Watch your step to avoid tripping.
USE extreme caution and be observant when working in close quarters or congested areas.
Before beginning work, familiarize yourself with the surroundings and circumstances of the site, such as obstacles in the
working and traveling area, the soil bearing capacity and any barriers separating the construction site from public
roads.
When traveling on public roads, ways and places always observe the valid traffic regulations and, if necessary, make
sure beforehand that the machine is in a condition compatible with these regulations
Always keep at a distance from the edges of building pits and slopes.
DO NOT run the engine in a closed building for an extended length of time. EXHAUST FUMES CAN KILL.
DO NOT operate the compactor on non-compactable material, such as concrete or hardened asphalt.
MAINTENANCE
Observe the adjusting, maintenance and inspection activities and intervals set out in the operating instructions,
including information on the replacement of parts and equipment. These activities must be executed by skilled
personnel only.
Ensure that the maintenance area is adequately secured.
After cleaning, examine all fuel, lubricant, and hydraulic fluid lines for leaks, loose connections, chafe marks and
damage.
Any defects found must be rectified without delay.
Always tighten any screwed connections that have been loosened during maintenance and repair.

SECTION 1 -
SAFETY PRECAUTIONS AND GUIDELINES
Any safety devices removed for set-up, maintenance or repair purposes must be refitted and checked immediately upon
completion of the maintenance and repair work.
Ensure that all consumables and replaced parts are disposed of safely and with minimum environmental impact.
AVOID, whenever possible, servicing, cleaning or examining the unit with the engine running.
NEVER fill the fuel tank, with the engine running, while near an open flame, or while smoking. ALWAYS wipe up any
spilled fuel immediately.
ALWAYS disconnect the spark plug before performing any work on the unit.
DO NOT alter the engine governor settings from those indicated in the engine manual.
ALWAYS replace damaged or lost decals. Refer to the Parts Manual for the proper location and part number of all
decals.
Carry out welding, flame-cutting and grinding work on the machine only if this has been expressly authorized, as there
may be a risk of explosion and fire.
Before carrying out welding, flame-cutting and grinding operations, clean the machine and its surroundings from dust
and other inflammable substances and make sure that the premises are adequately ventilated (risk of explosion).

Improper maintenance can be hazardous.
Read and understand SECTION 1 - SAFETY PRECAUTIONS AND GUIDELINES before you perform any maintenance,
service or repairs.
SAFETY CHECKS - PRE-STARTING
Before starting each day, in addition to the 10 hour daily routine maintenance, check or inspect the following items to
ensure trouble free performance.
1. Check fluid lines, hoses, fittings, filler openings, drain plugs, pressure cap, muffler, safety shrouds and the area
underneath.
2. The unit for signs of leakage or damage. Fix any leaks and correct any damage before operating.
3. Inspect the entire unit for damaged or missing parts and repair or replace them as needed.
4. Check the fuel level. If necessary, fill the fuel tank with the proper fuel.
5. Check all fastening hardware to ensure it is adequately tightened and that none is missing or broken.
6. Do not operate faulty equipment.
7. Be observant of people and obstructions within the work area.
Please read “INSTRUCTIONS FOR USE” for ROBIN engine and this instruction manual for correct use and care.

SECTION 4 - OPERATING INSTRUCTIONS
Please check if the unit is correctly maintained in good operating condition.
INSPECTION PRIOR TO OPERATION
CHECK ENGINE OIL
Before checking or refilling engine oil, be sure the compactor is located on a stable level surface.
Do not thread the gauge into oil filler to check oil level. If the oil level is below the lower level line on the dipstick, refill
with the proper oil to the upper level (to the neck of oil filler). See section 9.
CHECK ENGINE FUEL
Do not refuel while smoking, near an open flame or other potential hazards.
CLEANING AIR CLEANER
Check Air Cleaner to be sure it is clean and not contaminated. If it needs cleaning perform the following steps:
Remove the outer urethane foam and inner element. Wash the element in fuel. Saturate it in a mixture of 3 parts
kerosene or diesel fuel and 1 part engine oil. Shake off excessive oil and reinstall. Wash the air cleaner case using
kerosene. After cleaning it up, apply engine oil on the inner part of the case.
If the air cleaner element is seriously contaminated, engine start up failure, poor output or engine malfunction may
result.
CHECK EACH PART FOR LOSE OR BROKEN BOLTS AND NUTS
Tighten loose bolts and nuts, if any. Check each part for fuel or oil leak. Replace broken or damaged parts, if any, with
new ones.
LUBRICATION OF MAIN BODY
Check the Main Body oil level with the oil gauge before each operation. Change oil after the first 50 hours and every 200
hours. See Section 11.
