Ryobi Outdoor 3000 PSI 用户手册

16

When  servicing,  use  only  identical  Ryobi  replacement 
parts.  Use  of  any  other  parts  may  create  a  hazard  or 
cause product damage.

Always wear safety goggles or safety glasses with side 
shields  during  power  tool  operation  or  when  blowing 
dust. If operation is dusty, also wear a dust mask.

Before inspecting, cleaning or servicing the machine, shut 
off engine, wait for all moving parts to stop, and discon-
nect spark plug wire and move it away from spark plug. 
Failure to follow these instructions can result in serious 
personal injury or property damage.

Avoid  using  solvents  when  cleaning  plastic  parts.  Most 
plastics are susceptible to damage from various types of 
commercial solvents and may be damaged by their use. Use 
clean cloths to remove dirt, dust, oil, grease, etc.

Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact 
with  plastic  parts.  Chemicals  can  damage,  weaken  or
destroy  plastic  which  may  result  in  serious  personal 
injury.

Only the parts shown on the parts list are intended to be 
repaired or replaced by the customer. All other parts should 
be replaced at a Ryobi Authorized Service Center.
Before  running  the  engine,  perform  the  following 
pre-operation steps:
n 

Check that all bolts, nuts, etc. are securely tightened.

n 

�Make sure the air filter is clean.

n 

�Check both the engine oil level and the fuel tank level; 
refill as needed.

n 

�Inspect the work area for hazards.

n 

�If  there  is  excessive  noise  or  vibration,  stop  the  unit 
immediately.

See Figure 19.
A  dirty  air  filter  will  cause  starting  difficulty,  loss  of 
performance, and shorten the life span of the engine. Check 
the  air  filter  monthly.  If  working  in  dusty  soil,  clean  the 

air filter after each refueling. For best performance, replace 
the air filter at least once a year.
To clean the air filter:
n 

Remove the cover.

Fig. 19

n 

Lift the edge of the air filter carefully and pull it out.

n 

Wash the air filter with warm, soapy water.

n 

Rinse and squeeze to dry.

n 

Put small amount of 30 wt. motor oil on the filter sponge. 
Squeeze out the excess oil then reinstall the air filter.

 

NOTE:  Make sure the filter is seated properly inside the 
cover. Installing the filter incorrectly will allow dirt to enter 
the engine, causing rapid engine wear.

n 

Reinstall the cover.
