Instructions for Use

WARNING: Always observe the safety instructions and
applicableregulations.

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect tool from power
source before making any adjustments or removing/
installing attachments or accessories. Be sure the
trigger switch is in the OFF position. An accidental start-up
can causeinjury.
Proper Hand Position (Fig. A)

WARNING: To reduce the risk of serious personal injury,
Always use proper hand position as shown.

WARNING: To reduce the risk of serious personal injury,
always hold securely in anticipation of a sudden reaction.
Proper hand position requires one hand on the operating
handle
17
.
To Carry (Fig. A)
Fold down unit to position where you can carry the saw. Push in
the lock pin
1
to lock the armdown. Always carry the saw using
the carrying handle
19
.
Unlocking (Fig. A)
To unlock tool and raise head, depress motor arm slightly and
pull lock pin
1
out. Motor arm will then pivotupward.
Mounting (Fig. A)

CAUTION: Tool must be supported on stable, level,
non-skid surface to prevent unexpected movement
whenoperating.
1. Drill holes through the work surface that align the base of
the chopsaw.
2. Insert two M10 bolts down through the mounting holes
16
in the base and through holes in mounting surface. The
approximate length of the screws should be the thickness of
the mounting surface plus 102mm.
Spark Deflector Adjustment (Fig. A)

WARNING: Do not touch the spark deflector during or
immediately after operation as it becomes hot and may
cause skin burn.
To best deflect sparks away from surrounding persons and
materials, loosen the spark deflector screw
2
, adjust the spark
deflector
3
and then retighten screw. Do not allow cordset to
come into contact with deflector or sparks as damage to cordset
mayoccur.
Lock-Off Trigger Switch (Fig. A)
To turn the saw on, push the lock-off lever
14
to the left,
then depress the lock-off trigger switch
13
. The saw will run
while the switch is depressed. Allow the blade to spin up to
full operating speed before making the cut. To turn the saw
off, release the switch. Keep hands and material away from the
wheel until it has coasted to a stop. Allow the blade to stop
before raising the saw head. There is no provision for locking the
switchon.
Material Clamping and Supporting (Fig. B, C)
• Angles are best clamped and cut with both legs resting
againstbase.
• A spacer block
29
slightly narrower than the workpiece
30
can be used to increase wheel utilization (Fig.B).
• Long workpieces must be supported by a block
31
so it will
be level with top of base (Fig.C). The cut-off end
32
should
be free to fall downward to avoid wheelbinding.
Vise Operation (Fig. A, D)
The vise has a quick travel feature. To release the vise
6
when
it is clamped tightly, turn the crank
8
counterclockwise one or
two times to remove clamping pressure. Lift the vise lever
9
up. Pull crank assembly out as far as desired. The vise may
be shoved into work without cranking. Lower vise lever then
tighten vise on work by usingcrank.
Fence Operation (Fig. A, D, E)

WARNING: Turn off and unplug the tool before
making any adjustments or removing or installing
attachments or accessories. Be sure the trigger
switch is in the OFFposition.
The fence
5
can be adjusted two ways: to change desired
cutting angle and to change spacing between the fence
andvise.
To Change the Desired Cutting Angle
Use the 8 mm hex key
7
provided to loosen (do not remove)
the two fence bolts
15
. Align the desired angle indicator line
with the slot line
28
in the base
4
. Securely tighten both fence
bolts before use. For more accurate square cuts, disconnect the
power supply, loosen the two fence bolts, push arm down until
wheel extends into base. Place a square against the wheel and
adjust fence against the square. Securely tighten both fence
bolts before use. When making a miter cut, the vise
6
may not
clamp securely, depending on the thickness of the workpiece
and the miter angle. Other aids (such as spring, bar or C-clamps)
will be necessary to secure the workpiece to the fence when
making thesecuts.
Removal and Installation of Wheels
(Fig. F, G)

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect tool from power
source before making any adjustments or removing/
installing attachments or accessories. Do not make
any adjustment while the wheel is in motion. Do not
make any adjustment while chop saw is plugged into
powersupply.

WARNING: Always use gloves when handlingwheels.

WARNING: Do not impact the wheel, and do not use a
wheel that has been dropped or impacted. Do not use a
chipped, deformed or damagedwheel.
