SAFETY PRECAUTIONS
Please make sure you review each precaution carefully.
Pay special attention to statement preceded by the following words.
ENGLISH

WARNING “WARNING” indicates a strong possibility of severe personal injury or loss

of life if instructions are not followed.

CAUTION “CAUTION” indicates a possibility of personal injury or equipment damage

if instructions are not followed.

WARNING : EXHAUST PRECAUTIONS

■ Never inhale exhaust gasses.
They contain carbon monoxide, a colorless, odorless and extremely
dangerous gas which can cause unconsciousness or death.
■ Never operate the pump indoors or in a poorly ventilated area, such
FRANÇAISE

as tunnel, cave, etc.

■ Exercise extreme care when operating the pump near people
or animals.
■ Keep the exhaust pipe free of foreign objects.

WARNING : REFUELING PRECAUTIONS

■ Fuel is extremely flammable and its vapors can explode
if ignited.
■ Do not refuel indoors or in a poorly ventilated area.
■ Be sure to stop the pump prior to refueling.
■ Do not remove fuel tank cap nor fill fuel tank while engine is hot or
running. Allow engine to cool at least 2 minutes before refueling.
■ Do not overfill the fuel tank.
ESPAÑOL

■ If fuel is spilt, wipe it away carefully and wait until the fuel has dried
before starting the engine.
■ After refueling, make sure that the fuel cap is secured to prevent
spillage.

WARNING : FIRE PREVENTION

■ Do not operate the pump while smoking or near an open flame.
■ Do not use around dry brush, twigs, cloth rags, or other flammable
materials.
■ Keep cooling air intake (recoil starter area) and muffler side of the
engine at least 1 meter (3 feet) away from buildings, obstructions
and other burnable objects.
■ Keep the pump away from flammables and other hazardous
materials (trash, rags, lubricants, explosives).

WARNING : OTHER SAFETY PRECAUTIONS 1m

■ Be careful of hot parts.

The muffler and other engine parts become very hot while the 1m

pump is running or just after it has stopped. Operate the pump

in a safe area and keep children away from the running pump.
■ Do not use diaphram pump for the mixture of water and oil.
2
PTX301D ce_PU2365 07.5.14 4:08 PM ページ3

■ Do not touch the ignition cable when starting and operating the
engine.

ENGLISH
■ Operate the pump on a stable, level surface.
If the engine is tilted, fuel spillage may result.

NOTE
Operating the pump at a steep incline may cause seizure due
to improper lubrication even with a maximum oil level.

■ Do not transport the pump with fuel in tank or with fuel strainer cock open.
■ Keep the unit dry (do not operate it in rainy conditions).

CAUTION : PRE-OPERATION CHECKS

FRANÇAISE
■ Carefully check fuel hoses and joints for looseness and fuel leakage.
Leaked fuel creates a potentially dangerous situation.
■ Check bolts and nuts for looseness. A loose bolt or nut may cause
serious engine trouble.
■ Check the engine oil and refill if necessary.
■ Check the fuel level and refill if necessary.
Take care not to overfill the tank.
■ Keep cylinder fins and recoil starter free of dirt, grass and other debris.
■ Wear snug fitting working clothes when operating the engine.
Loose aprons, towels, belt, etc., may be caught in the engine or drive
train, causing a dangerous situation.
