Original instructions
life, always use blades with proper length and
suitable for the specific job and the processed
material.
WARNING:
The blade heats to high
temperature during operation. Do not touch
the blade immediately after ceasing operation
to avoid a possible burning. We recommend
to lay the saw down for a while until the blade
has cooled and to use protective gloves when
replacing a blade.
INSTALLING AND REPLACING THE
BLADE
1. Ensure that the plug is pulled out of the
supply socket.
2. Take the hex wrench (8) out of its hold
-
er (9).
3. Lay the machine down on a solid flat sur
-
face as shown on Fig. 2 Never place the ma
-
chine on the cord protector (7) while installing or
replacing the blade (13) - this may result in cord
damage and risk of electric shock.
4. Loosen the screw (10) until its head will
touch the cover wall.
5. Take out the old blade (13) carefully.
6. Position the new blade (13) in such a way,
that the centring pin (14) will engage in the cen-
tring opening of the blade shank.
7. Fasten the screw (10) carefully, until the
strap (11) will reach the blade (13).
8. Ensure that the blade (13) is properly posi
-
tioned in its strap (11).
9. Tighten the screw (10) firmly.
10. Place the hex wrench (8) back in its hold
-
er (9).
The careful and exact execution of the above
mentioned procedures guarantee the stable and
reliable fixing of the blade to the machine.
The blade is fixed by the forces acting between
the blade, the piston and the strap, as well as by
the precise profile groove in the strap, copying
the blade shank. The centring pin is used to ori-
entate initially the blade and it is not intended to
endure force loading during operation.
In case the blade has been mounted in a wrong
way the centring pin will endure force loading
and may warp or shear off, and the machine
has to be presented to the service centre for re-
placement of the centring pin.
Never operate the machine with a warped or
missing centring pin!
If the screw can not tighten the blade attaching
mechanism securely because the screw socket,
the screw thread or the hex wrench are worn,
the centring pin will warp or shear off. For this
reason replace the screw or the hex wrench well
before wear becomes excessive.
SWITCHING ON - SWITCHING Off
WARNING:
Before connecting the
power tool to a power source ensure that the
voltage supply is the same as the one speci-
fied on the nameplate of the machine.
▪ Switching on: Hold the saw firmly. Make sure
the blade does not touch any object. Push for-
ward the lock-on button (5), and then press the
ON/OFF switch (6).
The machine is equipped with soft-start elec-
tronics - the machine starts at low speed to
reach after 3-4 seconds the rated speed.
▪ Switching off: To stop operation release the
ON/OF switch (6).
STROKE RATE ADJUSTMENT
The optimum speed value for various materials
differs depending on a number of factors (kind of
material, blade type, accessibility to the working
