Maintenance - Black Max BM08570 Manuel De L'opérateur

WARNING:
When servicing, use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.
WARNING:
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.
WARNING:
Before inspecting, cleaning, or servicing the machine,
shut off engine, wait for all moving parts to stop, and
disconnect spark plug wire and move it away from spark
plug. Failure to follow these instructions can result in
serious personal injury or property damage.
GENERAL MAINTENANCE
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, lubricant, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating lubricants, etc., come in con-
tact 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 an Authorized Service Center.
REPLACING AND CLEANING AIR FILTER
See Figure 10.
A wet or dirty air filter can affect the way the engine starts,
performs, and wears. The air filter should be checked and
cleaned after 8 hours of operation. If working in dusty soil,
check the air filter after each refueling.
For best performance, the air filter should be replaced once
each year.
To clean the air filter:
 Loosen the knob on the air filter cover.
 Remove the cover.
 Lift the edge of the air filter carefully and peel it out.
 Wash the air filter with warm, soapy water.

MAINTENANCE

 Rinse and squeeze to dry.
 Reinstall the air filter.
 Reinstall the cover.
 Tighten knob to secure.
SPARk ARRESTOR
The muffler is equipped with a spark arrestor screen inside
muffler body. After extended use the screen can become
dirty and the screen may need to be replaced by an autho-
rized servicing dealer.
CLEANING THE EXHAUST PORT AND
MUFFLER
Depending on the type of fuel used, the type and amount of
lubricant used, and/or your operating conditions, the exhaust
port, muffler, and/or spark arrestor screen may become
blocked with carbon deposits. If you notice a power loss
with your gas powered tool, you may need to remove these
deposits to restore performance. We highly recommend that
only qualified service technicians perform this service.
FUEL CAP
The fuel cap contains a non-serviceable filter and a check
valve. A clogged fuel filter will cause poor engine per-
formance. If performance improves when the fuel cap is
loosened, the check valve may be faulty or filter clogged.
Replace the fuel cap if required.
SPARk PLUG
This engine uses a Champion RCJ6Y with 0.63 mm
(0.025 in.) electrode gap. Use an exact replacement and
replace annually.

A leaking fuel cap is a fire hazard and must be replaced
immediately.
