corrective actions to eliminate the cause of blade
binding.
-
When restarting a saw in the workpiece, centre
the saw blade in the kerf so that the saw teeth
are not engaged into the material.
If a saw blade
binds, it may walk up or kickback from the workpiece
as the saw is restarted.
-
Support large panels to minimise the risk of
blade pinching and kickback.
Large panels tend
to sag under their own weight. Supports must be
placed under the panel on both sides, near the line
of cut and near the edge of the panel.
-
Do not use dull or damaged blades.
Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade
binding and kickback.
-
Blade depth and bevel adjusting locking levers
must be tight and secure before making the cut.
If blade adjustment shifts while cutting, it may cause
binding and kickback..
-
Use extra caution when sawing into existing
walls or other blind areas.
The protruding blade
may cut objects that can cause kickback.
Lower guard function
-
Check the lower guard for proper closing before
each use. Do not operate the saw if the lower
guard does not move freely and close instantly.
Never clamp or tie the lower guard into the open
position.
If the saw is accidentally dropped, the
lower guard may be bent. Raise the lower guard
with the retracting handle and make sure it moves
freely and does not touch the blade or any other
part, in all angles and depths of cut.
-
Check the operation of the lower guard spring.
If the guard and the spring are not operating
properly, they must be serviced before use.
Lower guard may operate sluggishly due to
damaged parts, gummy deposits, or a build-up of
debris.
-
The lower guard may be retracted manually only
for special cuts such as "plunge cuts" and
"compound cuts". Raise the lower guard by the
retracting handle 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.
-
Always observe that the lower guard is covering
the blade before placing the saw down on bench
or floor.
An unprotected, coasting blade will cause
the saw to walk backwards, cutting whatever is in its
path. Be aware of the time it takes for the blade to
stop after switch is released.
Instructions on service and maintenance:
-
Regularly cleaning the machine, especially the
adjusting devices and guides, constitutes an
important safety factor.
-
Only original MAFELL spare parts and accessories
may be used. Otherwise the manufacturer will not
accept any warranty claims and cannot be held
liable.

Setting / Adjustment
4.1
Mains connection
Prior to commissioning make sure that the mains
voltage complies with the operating voltage stated on
the machine's rating plate.
4.2
Chip extraction
Connect the machine to a suitable external dust
extractor during all work generating a considerable
amount of dust. The air velocity must be at least 20 m/s
(65.6 ft / sec.).
The internal diameter of hose connector 1 (Fig. 1) is 35
mm (1 3/8 in.).
4.3
Saw blade selection
Use a sharp tool to obtain a good cut quality and select
a tool from the following list according to material and
application:
For cuts along and across the grain in soft or hard
wood:
-
TCT circular saw blade Ø 160 x 1.8 x 20 mm (6 ¼ x
5/64 in. x 20 mm), 32 teeth
For cuts especially along the grain in soft or hard
wood:
-
TCT circular saw blade Ø 160 x 1.8 x 20 mm (6 ¼ x
5/64 in. x 20 mm), 16 teeth
For cuts especially across the grain in soft or hard
wood:
-
TCT circular saw blade Ø 162 x 1.8 x 20 mm (6 3/8
x 5/64 in. x 20 mm), 48 teeth
