Care And Maintenance - Hilti WSR 1000 Manual De Instrucciones

7.1 Safe operation 6 7
CAUTION
The power tool must be pressed against the work-
piece until the contact shoe makes firm contact.
This helps ensure maximum safety and good perfor-
mance.
CAUTION
Always use saw blades that project at least 1½"
beyond the workpiece over the entire length of the
blade stroke. This will help to avoid violent kickback.
7.2 Switching on
The speed of the power tool can be varied contin-
uously up to maximum speed by slowly increasing
pressure on the control switch.
1. Plug the supply cord into the power outlet.
2. Press the control switch.
7.3 Switching off
Release the control switch.
7.4 Lockbutton for sustained operation
NOTE
The lockbutton for sustained operation allows the
motor to run continuously without need for constant
pressure on the control switch.

8. Care and maintenance

CAUTION
Ensure that the power tool is disconnected from the
electric supply.
8.1 Care and maintenance
Keep the blades clean, especially their connection
ends, in order to ensure trouble-free operation of the
blade holder.
Keep the blade holder clean.
The power tool has been adequately lubricated during
assembly. After a long period of heavy use it is
recommended that the power tool is inspected by
Hilti. This will help to extend the life of the power tool
and avoid unnecessary repair costs.

7.4.1 Switching on in sustained operating mode
1. Press the control switch fully.
2. While maintaining pressure on the control
switch, press the lockbutton and then release
the control switch.
7.4.2 Switching off after sustained operation
Press the control switch. The lockbutton returns to
its original position.
7.5 Plunge cutting 8
Use the plunge cutting technique only on soft ma-
terials. It takes a little practice to start the cut by
plunging the blade into the surface while the power
tool is running but without previously drilling a start-
ing hole. This is possible only with short saw blades.
For plunge cutting, the power tool may be used either
in the normal position or in the reversed position.
1. Bring the forward edge of the contact shoe into
contact with the surface of the material to be cut.
2. Press the control switch.
3. Press the forward edge of the contact shoe
against the surface and begin the plunge action
by slowly increasing the angle of attack. To
prevent stalling, it is important that the power
tool is running before the saw blade is brought
into contact with the surface.
4. Once the saw blade has penetrated right through
the material, bring the power tool into the normal
working position (contact shoe flush with the
workpiece) and then continue sawing along the
cutting line.
8.2 Care of the power tool
The outer casing of the power tool is made from
impact-resistant plastic. Sections of the grip are made
from a synthetic rubber material.
Never operate the power tool when the ventilation
slots are blocked. Clean the ventilation slots carefully
using a dry brush. Do not permit foreign objects to
enter the interior of the power tool. Clean the outside
of the power tool at regular intervals with a slightly
damp cloth. Do not use a spray, steam pressure
cleaning equipment or running water for cleaning.
This may negatively affect the electrical safety of the
power tool. Always keep the grip surfaces of the
en
