Your Compound Mitre Saw has been shipped completely
assembled except for the blade.

• Remove all loose parts from the carton. Separate and check

with the list of loose parts. 

See figure 1.

• Remove the packing materials from around your saw.

• Carefully lift saw from the carton and place it on a level 

work surface. Although small, this saw is heavy. To avoid 
back injury, get help when needed.

• Do not discard the packaging materials until you have

carefully inspected the saw, identified all loose parts and
satisfactorily operated your new saw.

• Your saw has been shipped with the saw arm locked in the

down position. To release saw arm, pull out the lock down
pin.

• Lift the saw arm by the handle. Hand pressure should

remain on the saw arm to prevent sudden rise upon release
of the lock down pin.

• Examine all parts to make sure no breakage or damage has

occurred during shipping.

If any parts are damaged or missing, do not attempt to plug in
the power cord and turn the switch on until the damaged or
missing parts are obtained and are installed correctly.
