INTRODUCTION
Congratulations on your purchase of a Polivac Gazda42/32 machine.
This machine has been designed to produce an optimum result with a minimum of effort and investment.
For you to receive the utmost from your investment and keep your machine serving you for many years to
come, you will need to establish a proper maintenance schedule.
Premature failure of the engine can be quite expensive and is the major reason for machine downtime.
It is essential that the items listed below are constantly addressed.
NB This manual should be read and implemented in conjunction
with the motor manufacturers manual.
1. OVERHEATING is the major cause of engine failure. Keep the cooling air debris filter clean.
Protect your machine and allow any foreign matter to build up on the cooling fins of the engine.
2. LOW AND DIRTY OIL is the next most common cause of the engine failure.
•Change the oil according to the motor manufacturers recommendations and check the
oil level and condition daily before each use.
3. YOUR GAZDA42/32 MACHINE MUST NEVER BE TILTED ON TO THE LEFT HAD SIDE
(VIEWING FROM BEHIND THE UNIT). – Follow sticker on the frame
•This will cause oil to seep into the carburettor and head of the engine, which will cause
excessive smoking and damage to the engine and regulator system.
USE AND CARE
Before using any new equipment, Polivac strongly recommends following safety precautions for all owners
and operators of gas-powered equipment.
SAFETY PRECAUTIONS
1. Polivac recommends the wearing of protective ear-wear as continuous exposure to high noise
levels may cause damage.
2. Do not touch the hot muffler/exhaust.
3. Do not allow any person to come in to contact with the rotating pad and keep other people
away from machine whilst it is in operation.
4. Do not leave machine unattended whilst running.
5. Do not leave machine accessible to untrained persons.
6. Do not operate the machine if the pad is off centre, damaged or missing. Substantial damage
to the floor, the machine or injury to personnel may result.
7. Vibration from machinery may cause numbness or tingling of the fingers in certain people.
Smoking, dampness, diet and heredity may contribute to the symptoms. Wearing warm
clothing gloves, exercising and refraining from smoking can reduce the effects of the machine.
8. The machine should be checked for any loose or damaged parts.
9. If a headache develops whilst machine is in operation it should be stopped and checked for
carbon monoxide emissions by a qualified repair agent.
10. If the smell of gas is evident, stop using the machine and take it outdoors. Have the source of
the leak repaired before continuing operation.
11. Never vent gas inside a building.
12. If your machine develops a high-pitched whistle, stop the engine and check the oil level. (Note
newer model are fitted with an alarm or cut off switch)

UNPACKING INSTRUCTIONS
Polivac gas buffers comes packaged in a palletised box designed to protect and secure the machine during
transportation. The machine is supplied with no gas cylinder. Before signing the delivery receipt, inspect the
packaging for damage (Remove box and check machine for damage). If damage is evident, note the damage
on the delivery receipt and contact your supplier.
MACHINE OPERATION
1. Adjust handle upright and tighten the bolt
2. Check the engine oil level and condition.
3. Secure the gas cylinder on a machine (at the back of the machine) and lock the screw bar.
4. Fit and secure gas cylinder hose.
5. Open gas cylinder valve.
STARTING THE ENGINE
1. Tilt the machine back
2. Set the throttle to the OFF position.
3. Press the Rocker/toggle switch to ON position
4. With the gas cylinder valve open, Press the foot switch until the engine begins operation,
which shouldn’t be any longer than 4-5 seconds (in a normal weather condition).
Run the engine at slow throttle position for approximately two minutes to allow efficient warm up. Advance to
full throttle and run machine. Preferably your machine should not be operated at anything less than full throttle
because a lower speed will cut down the incoming fresh air that is required for the cooling of the engine.
5. Drop the head of the machine on the floor and move forward
OPERATION OF GAZDA42/32
With the engine at full throttle & head on the floor machine will move forward.
When buffing, avoid any loose surfaces, electrical points, door trims and any object which may come in a
contact with the pads other than the floor itself.
1) If the machine moves excessively to left or right, then an adjustment need to be done to the knob
located at the right front (when standing behind the machine). Refer to yellow sticker for directions
2) Speed control screw is located at right front (when standing behind the machine). screw in further if
need to speed up and vice versa
3) Rich(red)/ Lean(blue) LED indicators on the emission motor to alternate between red and blue when
machine is working correctly. IF only the red or Blue LED illuminates, machine will stop in about 5
minutes. MUST get the assistance from qualified gas technician in that case.
STOPPING THE ENGINE
1. Tilt the machine back
2. Return the throttle to the OFF position
3. Close the gas cylinder valve
4. Turn the Rocker/Toggle switch to OFF position.
5. Remove the gas line hose from the cylinder.
6. Drop the head of the machine on the floor

IMPORTANT NOTICE
Polivac would like to direct your attention to the following issues so that correct and safe operation of your
gas-powered floor buffer is achieved. The superior performance of gas buffer has led to an increased demand
for the use of this type of floor maintenance equipment. This highlights the need for responsible
manufacturers, owners and operators to stress the importance of safety. These maintenance points are a
guideline to the upkeep of your machine. A more stringent program may be required depending on the type
and amount of use that your machine will be subject to.
DO’S
•DO check oil level before starting. It is important that the oil is maintained at the correct level for proper
lubrication and cooling of the engine. Consult the motor manufacturers manual for correct capacity
and oil specifications.
•DO check fuel level and hose connection before starting. The entire unit should be visually checked
for any loose or damaged hoses, fittings and connections.
•DO keep the debris filter clean (foam filter on top of motor) and free of any dust or lint. Any obstructions
to the cooling system can cause excessive heating and premature failure of the engine.
•DO change the oil at least every month / 140 Hours. One of the primary functions od the oil is to cool
the motor. When the oil is dirty or not kept to adequate levels it cannot cool the motor efficiently and
can cause premature failure resulting in costly repairs and down time.
•DO check belt tension before starting. Incorrectly adjusted belts will cause slipping and premature
wear. The belt should have approximately movement when depressed.
•DO carry out routine maintenance as specified. This will prevent any unnecessary down time of your
machine.
•DO run the machine at full throttle. Running the machine at a lower speed will cut down the incoming
fresh air that is required for the cooling of the engine.
•DO empty the dust bag after each use
DON’TS
•DO NOT overfill the gas bottle. Overfilling will cause severe damage to the motor and the gas
regulator.
•DO NOT tip the machine over on its left-hand side. If it is tipped on this side the oil in the motor will
run through the carburettor. This will cause the inability of the unit to start or excessive smoking if it
does start.
•DO NOT use starting fluid to assist with hard to start engines. Starting fluids can leave a hot spot on
the piston, which will cause premature failure of the engine.
•DO NOT apply unnecessary pressure up or down on the Buffing machine handle. Machine should
float easily across the floor.
•DO NOT over fill oil. Refer to the motor manufacturers manual for specifications and capacity.
•DO NOT buff any floor that has not been properly swept. Loose debris on the floor can become
hazardous flying missiles.

7
•DO NOT modify the unit in any way without the written permission of the Polivac International Pty.
Ltd. Any unauthorised modifications will void the warranty and Polivac International Pty. Ltd. Will not
be responsible for any damages to the unit or caused by the unit.
•DO NOT replace the pads or make any adjustment whilst the motor is running or the gas is turned
on.
