OPERATING INSTRUCTIONS
Grinding A Chain (cont.)
There is risk of serious
personal injury for chain-
saw operators or bystanders from improperly
sharpened saw chain. Read and follow all
manufacturer’s instructions for your saw chain.
Immediately unplug the
power cord if the motor
does not turn the wheel when the grinder power
switch is in the “on” position. Refer to page 5.
**Grounding Instructions.
1. For best results it is recommended that
the chain be clean before grinding.
2. Always wear approved eye protection
during all steps of the grind operation and
when the grinding wheel is in motion.
3. Grind all cutters of the same type (left or
right) before positioning the grinding wheel
to the opposite side.
4. When changing the grind position, make
sure the unit is turned to the “off” position
(white on/off switch or toggle on/off switch
located on the top of the motor support
arm) and the wheel has come to a full
stop before making any adjustments.
5. To avoid overloading the motor and to
prevent damage to the saw chain, remove
only the minimum amount of material nec-
essary and do not grind any one tooth for
too long a period. Using 2-3 light strokes
per cutter will help avoid the possibility of
any cutter burns.
6. Do not use cooling liquids while grinding.
7. Replace worn grinding wheels when the
diameter of the wheel reaches 70mm (2.8”).
D. Grinding for Bench or Wall Mounted
Workstations:
Note: All adjustments must be made prior
to applying power to the unit.
1. Position the saw chain to be ground onto
the vise (see Figure 13).
2. Setting top-plate cutting angle. Set
grinder head angle to correct degree (see
Figure 14 and see table 2, page 15 for
correct degree setting of different chain
types). If bench mounted, adjustment is
made by loosening adjustment knob #4,
page 4 (# 11 from exploded view, page 16),
at the back end of the grinder and rotating
the grinder head to the desired angle. (see
Figure 15). Or, if wall mounted, adjust
nut #2 on the backside of the unit.
3. Setting Vise for top-plate angle. To set
left-hand cutter top-plate grind angle, rotate
vise assembly to right of center (O
O
) (see
Figure 16). (See table 2, page 13 for correct
degree setting of different chain types.)
