WARNING!
To reduce the risk of serious personal injury, turn off the tool and disconnect it
from the power source before attempting to move it, change accessories or make any
adjustments.
WARNING!
To reduce the risk of serious personal injury, DO NOT touch the sharp points on
the blade with fingers or hands while performing any maintenance.
DO NOT use lubricants or cleaners (particularly spray or aerosol) in the vicinity of the
plastic guard. The polycarbonate material used in the guard is subject to attack by
certain chemicals.
• All bearings are sealed. They are lubricated for life and need no further maintenance.
• Periodically clean all dust and wood chips from around and under the base and the
rotary table. Even though slots are provided to allow debris to pass through, some
dust will accumulate.
• The brushes are designed to give you several years of use. If they ever need
replacement follow the instructions under BRUSH REPLACEMENT or return the tool to
the nearest service centre for repair.
WORKLIGHT CLEANING
For the best worklight performance, perform the following maintenance regularly.
• Carefully clean sawdust and debris from worklight lens with a cotton swab.
• DO NOT use solvents of any kind, they may damage the lens.
• Dust build-up can block the worklight and prevent it from accurately indicating the line
of cut.
• Follow mitre saw's instruction manual to remove and install blade.
• With blade removed from saw, clean pitch and build-up from blade. Pitch and debris
can interfere with the worklight and prevent it from accurately indicating the line of
cut.
DUST DUCT CLEANING
Depending on your cutting environment, saw dust can clog the dust duct and may
prevent dust from flowing away from the cutting area properly. With the saw unplugged
and the saw head raised fully, low pressure air or a large diameter dowel rod can be
used to clear the dust out of the dust duct.
REMOVING AND REPLACING BELT
(FIG. 37a-37b)
The belt is designed to last the life of the tool.
However, abuse of the tool could cause the
belt to fail.
If the blade does not turn when the motor is
running, the belt has failed. To inspect or
replace the belt:
• Loosen and remove four belt cover screws
(1) with flower wrench T25 (not supplied).
• Remove the belt cover (2). (Fig. 37a)
• Inspect the ribs of the belt for wear or failure.
• Check belt tension by squeezing the belt (3)
as shown in Fig. 37b. The belt halves should
almost touch when squeezing firmly with the
thumb and index finger.
• To adjust the tension, loosen but do not
remove the four set screws (4) with flower
wrench T25 (not supplied).
• Then rotate the set screw (5) with the wrench
(supplied) on the top of the motor plate
casing until the proper tension is achieved.
• Tighten the four set screws (4) securely.
• Replace the belt cover (2) and tighten four
belt cover screws (1).
CAUTION:
Overtightening the belt will cause premature
motor failure.
