WARNING!
Do not attempt to cut material that is larger than the maximum
cutting capacity of machine.
MITRE AND ANGLE CUTS (PIC.19)
NOTE: The rotating table has 5 positive stops at 0°, 15°, 22.5°,
30° and 45°.
Loosen the table locking knob, disengage the mitre latch (Pic.19)
(19.1) and rotate the table to the desired angle (Pic.19) (19.2).
Re-secure the table locking knob. Start the saw and release
the guard lock lever with your thumb. Make the cut through the
material in a smooth action.
BEVEL CUTS (PIC.20)
Loosen the bevel locking knob and tilt the saw head over to the
desired angle (Pic.20) (20.1). Re-secure the bevel locking knob.
Start the saw and release the guard lock lever with your thumb.
Make the cut through the material in a smooth action.
COMPOUND CUTS (PIC.21&22)
A compound cut is a combination of both mitre and bevel cuts.
Loosen the rotating table locking knob. Set the desired mitre
angle and re-secure the rotating table locking knob (Pic.21)
(21.1). Loosen the bevel locking knob and set the desired bevel
angle. Re-secure the bevel locking knob (Pic.22) (22.1). Start
the saw and release the guard lock lever with your thumb. Make
the cut through the material in a smooth action.
REPLACING THE BLADE (PICS.23 TO 30)
Warning! Never try to modify the motor spindle to accept any
other size blades or remove any of the guarding.
With the machine switched OFF and disconnected from the
mains supply.
BTL305:
Release the lock pin and allow the machine to rise upwards with
the guard in its closed position. Remove the guard operating
lever retaining screw (Pic.23) (23.1). Do not lose the screw.
Slacken the rear return spring housing retaining screw (Pic.23)
(23.2). Slacken the front return spring housing retaining screw
(Pic.23) (23.3), accessed through the hole in the guard. Press
the guard locking lever and with your other hand rotate the
plastic guard (Pic.24) (24.1) and return spring housing (Pic.24)
(24.2) in an anti-clockwise direction over the fixed blade guard
(Pic.24) (24.3) only enough to expose the blade securing bolt
(Pic.24) (24.4).
Note: The blade guard and return spring housing will require
wedging in place during blade removal and fitting.
BTL212 - BTL250:
Remove the cross head screw (Pic.37) (37.1) and pivot the
guard operating lever (Pic.37) (37.2) out of the way. Remove the
cross head screw (Pic.38) (38.1). and slacken the cross head
screw (Pic.38) (38.2). Release the guard lock and rotate the
blade guard and the return spring housing (Pic.39) (39.1) anti
clockwise until the return spring housing can be manoeuvred
clear of the cross head screw and the blade guard can be
removed.
REMOVING THE BLADE (PICS.25&28)
Using the box spanner supplied remove the blade securing
bolt (Pic.25) (25.1) unscrewing in a clockwise direction. At the
same time press in the spindle lock button (Pic.26) (26.1) until
it engages the spindle. Once the spindle is locked continue to
loosen the blade bolt. Remove the bolt and washer followed by
the blade securing flange (Pic.26) (26.2).
Caution!
The blade is very sharp and it is recommended that you use
safety gloves when handling blades. Manoeuvre the blade clear
of the spindle and dispose of at a re-cycling centre. Remove
the inner blade flange (Pic.27) (27.1) (noting which way round
it fits) and clean any accumulated debris from around the motor
spindle (Pic.28) (28.1).
FITTING A NEW BLADE (PICS.29 TO 31)
Fit the new blade over the motor spindle so that it locates on the
backing flange. Note the directional arrows on the blade (Pic.29)
(29.1) should point in a clockwise direction, i.e. with the teeth
pointing downwards.
The motor spindle is machined with two flats which correspond
to the two flats machined in the blade securing flange bore
(Pic.30) (30.1). Fit the blade securing flange over the motor
spindle aligning the flats. Offer the blade securing bolt and
washer to the motor spindle threads (Pic.31) (31.1) and turn in
an anti-clockwise direction until finger tight. Press in the spindle
lock and tighten the blade bolt to a moderate torque.
Release the spindle lock and check that the blade rotates freely.
Return the blade guard and return spring housing to their original
positions. Secure the return spring housing by tightening the
two securing screws, ensuring that the front screw is correctly
located in the return spring housing. Allow the blade guard to
return to its original position and re-secure the guard operating
lever with the retaining screw ensuring that the shoulder on
the retaining screw is correctly located in the slot in the guard
operating lever. Check that the guard operates correctly by
lowering and raising the cutting head assembly.
Re-check all adjustments and settings periodically for
accuracy.
Warning: It is important that the blade guard is fitted and
operates correctly
BTL305:
OVERLOAD PROTECTION (PIC.31)
This machine is fitted with an overload protection switch. If after
extended use the machine unexpectedly stops or fails to start.
Allow the machine to cool down before re-setting the overload
switch (Pic.31) (31.2).
LASER SAFETY
The Laser guide line used in this product uses a class 2 Laser
with a maximum power output of 1.5mW at a wave length of
between 635 and 670nm. These lasers do not normally present
an optical hazard, although staring at the beam may cause
temporary flash blindness.
