Deploy the stop by moving it outwards, Fig.20. If the trenching stop
wont move, slightly loosen the screw using a crosshead
screwdriver.
This restricts the cut to a “trench” in the workpiece.
The depth of the trench can be adjusted with the trenching depth
adjustment screw and locked in position with the trenching depth
lock nut (Fig.21).
OPERATION
Make a cutting line on the wood board by pen, and turn the laser
switch on and make the laser line coincidence with the cutting line
on the board. (Fig 22)
To turn the saw on press the switch lock to the left.
Hold the operating handle firmly and squeeze the switch trigger,
(Fig.23).
When the blade is at its maximum speed (approximately 2
seconds), lower the blade through the workpiece (Fig.24). After
completing the cut, release the switch trigger and allow the saw
blade to stop rotating before raising the blade out of the workpiece.
Wait until the blade stops before removing the workpiece.
CHOP CUTTING (WITHOUT SLIDING FUNCTION)
To saw narrow pieces of wood, the slide function is not necessary.
In these cases, ensure that the slide lock is screwed down to
prevent the saw arm from sliding, Fig.25.
A crosscut is made by cutting across the grain of the workpiece. A
90
0
crosscut is made with the mitre table set at 0
0
. Mitre crosscuts
are made with the table set at some angle other than zero.
Pull on the release knob and lift the saw arm to its full height.
Loosen the mitre lock. Rotate the mitre table until the pointer aligns
with the desired angle. Retighten the mitre lock.
WARNING. Be sure to tighten the mitre lock before making a cut.
Failure to do so could result in the table moving during the cut and
cause serious personal
injury.
Place the workpiece flat on the table with one edge securely
against the fence. If the board is warped, place the convex side
against the fence. If the concave side is placed against the fence,
the board could break and jam the blade.
When cutting long pieces of timber, support the overhanging ends
of the timber with the side extension arms, a roller stand or a work
surface that is level with the saw table.
Use the clamp assembly to secure the workpiece wherever
possible.
It is possible to remove the clamp assembly by loosening the clamp
assembly lock and moving it to the other side of the table. Make
sure the clamp assembly lock is tight before using the clamp.
Before turning on the saw, perform a dry run of the cutting
operation to check that there are no problems.
Press the switch lock to the left. Hold the operating handle firmly
and squeeze the switch trigger. Allow the blade to reach maximum
speed.
Slowly lower the blade into and through the workpiece.
Release the switch trigger and allow the saw blade to stop rotating
before raising the blade out of the workpiece. Wait until the blade
stops before removing the workpiece.
CROSS-CUTTING (WITH SLIDE ACTION)
When cutting wide workpieces, first unscrew the slide lock, Fig.25.
Pull on the release knob, raise the saw arm to its highest position
and slide it towards you.
Press the switch lock to the left. Hold the handle firmly and
squeeze the switch trigger. Allow the blade to reach maximum
speed. Press the release latch and slowly lower the blade into the
workpiece and slide it away from you at the same time until the
workpiece is cut.
Release the switch trigger and allow the saw blade to stop rotating
before raising the blade out of the workpiece.
Wait until the blade stops before removing the workpiece.
BEVEL CUT
A bevel cut is made by cutting across the grain of the
workpiece with the blade angled to the fence and mitre
table. The mitre table is set at the zero degree position
and the blade set at an angle between 0
0
and 45
0
to the
left, Fig.26.
Repeat the steps for cross-cutting (with or without slide
function).
Loosen the bevel lock and move the saw arm to the left to
the desired bevel angle (between 0o and 45
0
).
Tighten the bevel lock.
WARNING: Always ensure that the bevel lock is fully
tightened before making a cut.
COMPOUND MITRE CUT
A compound mitre cut involves using a mitre angle and a
bevel angle at the same time.
It is used in making picture frames, to cut mouldings,
making boxes with sloping sides and for roof framing.
Always make a test cut on a piece of scrap wood before
cutting into the good material.
Use the slide action when cutting wide workpieces.
MAINTENANCE & CARE
CHANGING A BLADE
DANGER: The blade is extremely sharp and care must be
observed when handling. Never try to use a blade larger
than the stated capacity of the saw. It might come into
contact with the blade guards. Never use a blade that is
too thick to allow the outer blade washer to engage with
the flats on the spindle.
It will prevent the blade bolt from properly securing the
blade on the spindle.
Do not use the saw to cut metal or masonry.
Ensure that any spacers and spindle rings that may be
required suit the spindle and the blade fitted.
Make sure that the battery is removed from the machine.
Push down on the operating handle and pull the release
knob to disengage the saw arm.
The release knob can be turned so that it is held in the
retracted position.
Raise the saw arm to its highest position.
Rotate the lower blade guard (Fig.27) up and into the
upper blade guard and press the spindle lock button
(Fig.28). Rotate the blade until the spindle locks.
Use the 6mm Allen key wrench to remove the blade bolt
(Fig.29). (Loosen in a clockwise direction as the blade
screw has a left hand thread).
Remove the washer, outer blade flange and the blade.
Wipe a drop of oil onto the inner blade washer and the
outer blade washer where they contact the blade.
Fit the new blade onto the spindle taking care that the
inner blade washer sits behind the blade.
CAUTION. To ensure correct blade rotation, always install
the blade with the blade teeth and the arrow printed on
the side of the blade pointing down (Fig.29).
The direction of blade rotation is also stamped with an
arrow on the upper blade guard.
Replace the outer blade washer.
Depress the spindle lock button and replace the blade
bolt.
Use the 6mm Allen key wrench to tighten the blade screw
securely (anti-clockwise).
Check that the blade guard operates correctly and
covers
the blade as the saw arm is lowered.
Connect the battery to the machine and run the saw to
make certain that it is operating correctly.
Note: Check the tightness of the blade securing bolt
before, during and after each use.
