Operating the Washer
sTarTing and OPeraTing engine
CAUTION: Do not run engine in an enclosed area.
exhaust gas contains carbon monoxide, an odorless and
poisonous gas that can cause sickness or death.
iMPOrTanT: To prevent possible pump damage, do not allow
washer pump to run in bypass (with gun trigger
released) for longer than 3 minutes.
IMPORTANT: During first two hours of engine operation, engine

moving parts break in.

be operated with the throttle in the FAST or HIGH position

and squeeze gun trigger. If trigger is not squeezed while pulling
recoil starter, pressure will build up until recoil starter can not
be pulled over.

bystander or objects. Pressurized output spray will start
almost instantaneously at engine start-up and can cause
serious personal injury or property damage. Release
trigger immediately upon engine start.

briskly until engine starts.

engine. Return it gently to prevent damage to
starter.

up enough to run smoothly. If engine is warm, push choke
lever in as soon as engine starts.
