General Maintenance; Maintenance; Chain Tension - Homelite UT43160 Manual Del Operador

WARNING:
When servicing, use only identical replacement
parts. Use of any other parts may create a haz-
ard 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 may
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).

MAINTENANCE

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.
