Maintenance - Metabo KS 18 LTX 66 BL Original Instructions Manual

en ENGLISH
Open the lower guard by hand only for special cuts,
e.g. angled cuts. Raise the lower guard by the
retracting handle (7) and as soon as the blade
enters the material, the lower guard must be
released For all other sawing, the lower guard
should operate automatically.
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.
Sawing along a straight line: the cutting indicator
is used here (12). 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°.
Note: When sawing without parallel guide/rip fence,
insert it the other way around and thus increase the
stability of the machine.
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 parallel guide:
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 (15). Fix using both clamping levers (2). 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.
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.
Press in the spindle locking button (32) and hold in
place. Turn the saw spindle slowly with the spanner
(20) in the saw blade fixing screw (27) until the lock
catches.
Unscrew the saw blade fixing screw in anti-
clockwise direction and remove the outer saw blade
16
flange (28). Pull back the movable guard (31) and
remove the saw blade.
Ensure that the inner saw blade flange (30) is
inserted in the right way: The inner saw blade
flange (30) 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 (30)! 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 (30), the saw blade (29), the outer saw blade
flange (28) and the saw blade fixing screw (27) must
be clean.
Put on the outer saw blade flange (28). Ensure that
the outer saw blade flange (28) is inserted the
correct way round.
Tighten the saw blade fixing screw (27) using a
hexagon wrench (20) (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.
8.2 Correcting the saw blade angle
The saw blade angle has been adjusted at the
factory.
If necessary, the saw blade angle can be adjusted
for 0° and for 45°. Turn 2 adjustment screws (26)
(for 0°) or adjustment screw (10) (for 45°).
9. Cleaning
Remove battery pack from machine.
Dust deposits must be regularly removed from the
machine. This includes cleaning the ventilation slits
on the motor with a vacuum cleaner. Make sure that
the safety appliances, e.g. the movable guard, are
in perfect working order.
f 10. Accessories
Use only original Metabo or CAS (Cordless Alliance
System) battery packs and accessories.
