WARNING:

When servicing, use only identical replacement

parts. Use of any other parts could create a

hazard or cause product damage.

WARNING:

Always wear eye protection with side shields

marked to comply with ANSI Z87.1, along with

head protection. Failure to do so could result in

objects being thrown into your eyes and other

possible serious injuries.

WARNING:

Before inspecting, cleaning or servicing the unit,

stop the motor, wait for all moving parts to stop,

and disconnect from power supply. 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, oil, grease, etc.

WARNING:

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 could

result in serious personal injury.

All chain saw service, other than the items listed in

the instruction manual maintenance instructions,

should be performed by competent chain saw

service personnel. (For example, if improper tool

is used to hold the flywheel in order to remove

the clutch, structural damage to the flywheel could

occur and subsequently could cause the flywheel

to burst).

CHAIN TENSION

See Figures 11 - 12.

WARNING:

To avoid possible serious injury, never touch or

adjust the chain while the motor is running. The

saw chain is very sharp; always wear protec-

tive gloves when performing maintenance to

the chain.

 Stop the motor and disconnect from power

supply before setting the chain tension. Make

sure the guide bar nut is loose to finger tight,

turn the chain tensioning screw clockwise to

tension the chain. Refer to Replacing the Bar

and Chain for additional information.

NOTE: A cold chain is correctly tensioned when

there is no slack on the underside of the guide

bar, the chain is snug, but it can be turned by

hand without binding.

 Chain must be re-tensioned whenever the flats on

the drive links hang out of the bar groove as

shown in fig. 11.

 During normal operation, the temperature of the

chain will increase. The drive links of a correctly

tensioned warm chain will hang approximately

.050 in. out of the bar groove, as shown in

fig. 12.

FLATS

APPROX .050 in.
