•ALWAYS shut off engine and allow it to cool a least 2 minutes before adding
fuel to the tank
•ALWAYS use care in filling tank to avoid spilling fuel. Move pressure washer
away from fuelling area before starting engine.
•ALWAYS keep maximum fuel level below top of tank to allow for expansion.
•ALWAYS operate and use equipment in well ventilated areas free from
obstructions. Equip areas with fire extinguishers suitable for gasoline fires
•NEVER operate pressure washer in an area containing dry bush or weeds.
•ALWAYS keep pressure washer a minimum of 1.2m away from surfaces (such
as houses, automobiles, or live plants) that could be damaged from muffler
exhaust heat.

inhaled or ingested, causing severe nausea, fainting
or poisoning.
•ALWAYS operate pressure washer in a well-ventilated area. Avoid enclosed
areas such as garages, basements etc.
•ALWAYS keep exhaust gas from entering a confined area through windows,
doors, ventilation intakes, or other openings.
•ALWAYS follow manufacturer’s recommendations, use a respirator or mask
whenever there is a chance that vapours may be inhaled.
•If the operating area becomes enclosed, turn off engine and release system
pressure by pulling gun trigger. Immediately leave the affected area.
WARNING
RISK OF FALL HAZARD
•Use of pressure washer can create puddles and
slippery surfaces.
•Kick back from spray gun can cause you to fall.
•Keep operating area clear of all persons, pets and obstacles.
•DO NOT operate the product when fatigued or under the influence of alcohol
or drugs. Stay alert at all times.
