Changing Saw Blades - Metabo KT 18 LTX 66 BL Manual Original

7.3 Working Directions
Do not switch the machine on or off while the
saw blade is touching the workpiece.
Let the saw blade reach its full speed before
making a cut.
When sawing, never remove the machine
from the material with the saw blade turning.
Allow the saw blade to come to a standstill.
If the saw blade blocks, turn the machine off
immediately.
Do not set the machine down until the saw
blade has come to a standstill.
Plunge cuts: The motor section is in the upper
position, the saw blade does not project from the
guide plate. Hold the machine tightly with both
hands and place with the guide plate onto the
workpiece. Switch on the machine. Lower the motor
section slowly to the set cutting depth and then
move slowly in cutting direction.
Sawing along a straight line: the cutting indicator
is used here (2). The left edge (marked red)
indicates the direction of the cut if the saw blade is
held vertically. The right edge indicates the
direction of the cut if the saw blade is held at 45°.
Sawing along a rail secured on the workpiece:
In order to achieve an exact cutting edge, you can
attach a rail to the workpiece and then guide the
hand-held circular saw by means of the guide plate
along this rail.
Sawing with a rip fence (see Accessories
chapter):
For cuts parallel to a straight edge. The rip fence
can be inserted from either side into the support
provided for it. The cut width can be read off at the
mark (8). Fix using both clamping levers (1). It is
best to calculate the exact cut width by making a
test cut.
Sawing with a guide rail (see Accessories
chapter):
For dead straight, tear-free cutting edges with
millimetre precision. The anti-slip coating keeps the
surface safe and protects the workpiece against
scratches. See Accessories section. The rotary
button (15) is used for setting a clearance-free fit.
Battery pack heat generation:
Under extremely hard application conditions
(e.g. sawing thick wooden planks), the heavy load
can cause the battery pack to heat (> 60 °C). To
conserve the battery pack, allow it to cool down
before continuing work.
8. Maintenance
8.1

Changing saw blades

The saw blade must be stationary.
Remove battery pack from machine.
Risk of injury, even with the blade at standstill.
Wear protective gloves.
See figure page 3.
1. Press the locking button (13) and move.
2. Move in such a way that the read-off edge (10) is
pointed to the symbol "saw blade changing".

3. Release the locking button (13) again.
4. Turn the lever (14) clockwise up to the stop.
5. Push the locking button (17) forwards and lower
the motor section a little. Release the locking
button (17) again.
6. Push the motor section down until it locks in
place at the stop.
Changing
Turn the saw spindle slowly with the spanner in the
saw blade fixing screw (30) (24)until the lock
catches.
Unscrew the saw blade fixing screw in anti-
clockwise direction and remove the outer saw blade
flange (31). Remove the saw blade.
Ensure that the inner saw blade flange (33) is
inserted in the right way: The inner saw blade
flange (33) has 2 sides, diameter 20 mm and 5/8"
(16 mm). Ensure a precise fit of saw blade mounting
hole to the inner saw blade flange (33)! Incorrectly
installed saw blades do not run smoothly and lead
to loss of control.
Insert a new saw blade, Make sure the direction of
rotation is correct. The direction of rotation is
indicated by arrows on the saw blade and guard.
The contact areas between the inner saw blade
flange (33), the saw blade (32), the outer saw blade
flange (31) and the saw blade fixing screw (30) must
be clean.
Put on the outer saw blade flange (31). Ensure that
the outer saw blade flange (31) is inserted the
correct way round.
Tighten the saw blade fixing screw (30) using a
hexagon wrench (24) (max. 5 Nm).
Use only sharp, undamaged saw blades. Do
not use saw blades that are cracked or that
have changed their shape.
Do not use any saw blades made from high-
alloy high-speed steel (HSS).
Do not use any saw blades which do not
conform to the specified rating.
Use only saw blades with a diameter according to
the markings on the saw.
The saw blade must be suitable for the no-load
speed.
Use a saw blade that is suitable for the
material being sawn.
Use only genuine Metabo saw blades. Saw
blades intended for cutting wood or similar
materials have to conform to EN 847-1.
