PREPARATION FOR OPERATION
BLADE INSTALLATION
The wall chaser is designed to work with special compound multi-
blades
• Use included keys and hold the outer flange (10) to lock the spindle
and undo the fixing screw (9) (fig. A, B). The fixing screw has left hand
thread.
• Remove the fixing screw (9) and remove the outer flange (10) (fig. A).
• Insert blade under the guard and install blade onto the spindle.
• Well seated blade must rest on the spindle flange (11) (fig. A). The
spindle does not go through full depth of blade installation hole.
• Slide the outer flange into the blade hole. Rotate the outer flange
while pressing it, until it goes into the hole so it fully rests on the
blade surface.
• Screw in the fixing screw.
• Use the keys to lock the spindle and tighten the fixing screw (fig. B).
You can remove the blade by following the installation procedure in
reverse sequence.
DUST BAG INSTALLATION
The wall chaser comes with a dust bag, adjustable shoulder strap and
hose with adapters to connect the dust bag to the wall chaser.
• Undo one of the adapters (13) attached to hose end (12) (fig. C). Left
hand thread is used.
• Slide down the clamp (15) to open the dust bag (14) (fig. D).
• Put removed adapter through the hole for emptying (16) of the dust
bag and slide it into the inlet hole (17) (fig. D). Its narrow end should
partially protrude outside.
• Put on and tighten the metal hose clamp where adapter joins with
the dust bag, then connect the hose to the adapter (fig. E).
• Slide the other end of the hose with adapter (13) onto the dust
extraction outlet (7) (fig. F) and rotate clockwise until it locks.
• Adjust length of the shoulder strap (18) for comfortable use of the
dust bag (14) (fig. D).
Deinstallation is similar to the installation procedure in reverse
sequence.
CONNECTION OF DUST EXTRACTION SYSTEM
For cleaner workplace you can attach external dust extraction device
to the wall chaser.
Connect the dust extraction hose tip to the dust extraction outlet
(7). Make sure to use adapter with large enough diameter for secure
connection.
When starting to work, first switch on the dust extraction system, e.g.
industrial vacuum cleaner, next switch on the wall chaser. When the
work is finished proceed inversely – switch off the wall chaser first,
next the vacuum cleaner. This procedure allows to avoid unnecessary
dustiness in the workplace. Some types of industrial vacuum cleaners
are equipped with power supply socket for power tools and switching
the vacuum cleaner on and off is automated, controlled with switching
the power tool.
SETTING CHASE DEPTH
Set the chase depth before starting to work and with the device
switched off.
• Move the lock lever (6) back to loosen it.
• For greater cutting depth move the front handle (5) backward, to
reduce depth move it forward.
• Setting correct depth is easier with depth gauge and scale located
on the blade body.
• Once the correct depth has been set, tighten the lock lever (6) by
moving it forward.
OPERATION / SETTINGS
Check condition of the blade before using the power tool. Do not use
blades with dents, cracks or other damages. Replace worn out blade
with a new one before operation. After work is finished always switch
the power tool off and wait until the work tool comes to complete
stop. Only then you can put the power tool away.
• Cutting blade must be installed properly and must be free to
rotate.
• Never overload the wall chaser. Overloading and too strong
pressure may cause dangerous cracks in the cutting blades.
• Never hit processed material with working tool.
• Never use blades for wood cutting designed for circular sawing
machines. Use of such blades often results in the power tool
kickback, losing control and may cause operator body injury.
SWITCHING ON / SWITCHING OFF
The mains voltage must match the voltage on the rating plate of the
wall chaser. Hold the power tool with both hands when starting and
during operation.
The wall chaser features switch that protects against unintentional
starting up.
• Press the switch lock button (1) (fig. C).
• Press the switch button (2) (fig. C).
• Release pressure on the switch button (2) to stop the wall chaser.
WORKING WITH WALL CHASER
The wall chaser is designed only for straight cuts. Making curved or
round cuts is forbidden. The tool is designed for dry operation only.
Before starting to work examine the place where the operation
will take place, check for hidden plumbing, electrical and gas
installations. You can find it with special device for wire localization.
The wall chaser is equipped with a soft start feature. Wait a while after
starting the wall chaser until the blade reaches its top speed, only
then you can proceed with your work. When working, do not use the
switch of the wall chaser to switch it on or off. Switch button may only
be used when the wall chaser is away from the processed material.
MAKING A CHASE
• Set the cutting depth.
• Put the rear guide roller (3) against the wall (cutting blades should be
above the wall surface) (fig. H).
• Start the wall chaser and wait until cutting blades reach full rotational
speed.
• Gradually lower the wall chaser and plunge the cutting blades into
the wall (during this move rear guide roller should have contact with
the wall surface).
• As soon as the front guide roller (4) rests on the wall, continue with
the cut and move the wall chaser forward and away from you (in
direction opposite to rotation of cutting blades).
• End the cut in reversed starting sequence: by lifting the front guide
roller and the cutting blade. Keep the rear guide roller against the
wall at all times.
