Use a finer blade for ferrous metals and a coarse blade for non-
ferrous metals.
When cutting thin gauge sheet metals,
ALWAYS clamp wood on
both sides of the sheet. This will give you a clean cut without excess
vibration or tearing of the metal.
DO NOT
force the cutting blade. Forcing the blade will reduce blade
life and cause the blade to break.
Note:
We recommend that you spread a thin film of oil or other
coolant along the line of cut ahead of the saw. This will allow easier
operation and help extend blade life. When cutting aluminum, use
kerosene.
POCKET CUTTING (Soft materials only) (See Fig. J, K)
Mark the pocket or internal hole to be cut out. Insert the special
cutting blade with blade teeth facing down and clamp securely. Angle
the saw so that the back edge of the blade guard is resting on the
work surface. Use a slow speed to start the cut to avoid breaking the
blade but increase to correct speed once the cut has started. With
the blade guard held firmly against the work surface, start a slow
but controlled upward swing of the saw. The blade will cut into and
through the material. Always ensure the blade is completely through
the material before cutting the remainder of the pocket.
REPLACING CARBON BRUSHES (See Fig. L)
Remove and check the carbon brushes regularly. When they are
worn to length of about 6mm, both new carbon brushes should be
replaced at the same time. When changing worn carbon brushes,
use a slotted screwdriver to remove the brush holder caps. Take out
the worn carbon brushes, insert the new ones and make sure the
carbon brushes moving freely in the brush holders. Finally, secure the
brush holder caps.

Work hints for your reciprocating
saw
If your power tool becomes too hot, set the speed to maximum and
run a no load for 2-3 minutes to cool the motor.
Always ensure the work-piece is firmly held or clamped to prevent
movement.
The pivot foot plate must be held firmly against the material being cut
to reduce saw vibration, blade jumping and blade breakage.
Maintenance
Remove the plug from the socket before carrying out any
adjustment, servicing or maintenance.
Your power tool requires no additional lubrication or maintenance.
There are no user serviceable parts in your power tool. Never use
water or chemical cleaners to clean your power tool. Wipe clean with
a dry cloth. Always store your power tool in a dry place. Keep the
motor ventilation slots clean. Keep all working controls free of dust.
Occasionally you may see sparks through the ventilation slots. This is
normal and will not damage your power tool.
If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified persons in order
to avoid a hazard.
