OPERATION

Instructions for Use
WARNING: Always observe the safety instructions and
applicable regulations.
To Carry (Fig. A)
Fold down unit to position where you can carry the saw. Push in
lock pin to lock arm down.
1
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. D, F)
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
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.
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 , with the other hand guiding the workpiece.
Spark Deflector Adjustment (Fig. A)
To best deflect sparks away from surrounding persons and
materials, loosen the spark deflector screw
deflector and then retighten screw. Do not allow cordset to

come into contact with deflector or sparks as damage to cordset
may occur.
Trigger Switch (Fig. A)
To start the tool, depress the trigger switch
off, release the trigger switch. Keep hands and material from
wheel until it has coasted to a stop.

To prevent unauthorized use of tool, install a standard padlock
(not included) into the padlock hole
Material Clamping and Supporting (Fig. B, C)
• Angles are best clamped and cut with both legs resting
against base.
• A spacer block slightly narrower than the workpiece can be
used to increase wheel utilization (Fig. B).
• Long workpieces must be supported by a block so it will be
level with top of base (Fig. C). The cut off end should be free
to fall downward to avoid wheel binding.
Vise Operation (Fig. D)
The vise 6 has a quick-travel feature. To release the vise when
it is clamped tightly, turn the crank
two times to remove clamping pressure. Lift vise lever
Pull crank assembly out as far as desired. Vise may be pushed
forward into work without cranking. Lower vise lever
tighten vise 6 on work by using crank
Fence Operation (Fig. A, E, F)
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
1. Use the hex key
two fence bolts
with the slot line
fence bolts before use.
2. For more accurate square cuts, disconnect the power supply,
loosen the two fence bolts, push arm down until wheel
16
extends into base. Place a square against the wheel and
adjust fence against the square. Securely tighten both fence
bolts before use.
3. When making a miter cut, the vise
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.
To Change Spacing Between the Fence and
Vise
Using the hex key
fence bolts 13 . Adjust the fence
both fence bolts in provided locations. Securely tighten both
fence bolts before use.
Removal and Installation of Wheels
(Fig. A, G, H)
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. Do not make any adjustment
while the wheel is in motion. Do not make any adjustment
while chop saw is plugged into power supply.
