ASSEMBLY

WARNING: To reduce the risk of injury, turn unit off and
disconnect machine from power source before installing and
removing accessories, before adjusting or changing set-ups
or when making repairs. Be sure the trigger switch is in the OFF
position. An accidental start-up can cause injury.
Unpacking
The motor and guards are already assembled onto the base.
Cable Clamp (Fig. C)
Verify the cable runs through the cable clamp
the saw head to travel, then tighten the clamp by means of the screw.
Bench Mounting (Fig. B)
1. Holes 18 are provided in all four feet to facilitate bench mounting.
Two different sized holes are provided to accommodate different sizes
of bolts. Use either hole; it is not necessary to use both. Always mount
your saw firmly to prevent movement. To enhance the portability, the
tool can be mounted to a piece of 12.5 mm or thicker plywood which
can then be clamped to your work support or moved to other job sites
and reclamped.
2. When mounting your saw to a piece of plywood, make sure that the
mounting screws do not protrude from the bottom of the wood.
The plywood must sit flush on the work support. When clamping the
saw to any work surface, clamp only on the clamping bosses where
the mounting screw holes are located. Clamping at any other point will
interfere with the proper operation of the saw.
3. To prevent binding and inaccuracy, be sure the mounting surface is not
warped or otherwise uneven. If the saw rocks on the surface, place a
thin piece of material under one saw foot until the saw is firm on the
mounting surface.
Assembling the Base Extensions (Fig. V)

WARNING: Base extensions must be assembled to both sides of
the saw's base before using the saw.
1. Locate the holes above the hand indentations on the side of the base.
2. Using a hex wrench, attach the bolt
the base extension handle 20 , and into the holes on the base.
3. Ensure the extension is secure by pulling on the extension to verify
no movement.
4. Repeat steps 1 through 3 on the other side.
nOTE: Make sure the extensions are level with the work surface so that the
workpiece rests evenly. A straight workpiece should have no gap between it
and the base extensions.
Changing or Installing a New Saw Blade (Fig. A, D, E)

WARNING: To reduce the risk of injury, wear gloves when handling
the saw blade.

WARNING: To reduce the risk of injury, turn unit off and
disconnect machine from power source before installing and
removing accessories, before adjusting or changing set-ups
or when making repairs. Be sure the trigger switch is in the OFF
position. An accidental start-up can cause injury.
• Never lock the spindle while the blade is under power or coasting.
• Do not cut light alloy and ferrous metal (containing iron or steel)
or masonry or fibre cement product with this mitre saw.
