6.3
replacing the velcro backing pad
(Pages *16* and *17*)
Only use OEM backing pads! Place the Allen key
into the screw head of the driving disk attachment
bolt on the drive shaft (1k.). Hold the backing
pad with one hand, while using the Allen key to
unscrew the attachment bolt (in anti-clockwise
direction) from the drive shaft (2k.). Now you can
lift the backing pad off the drive shaft.
Attach the new backing pad in reverse order of
these work steps and use the Allen key to screw
in the attachment bolt (in clockwise direction). (1l.
and 2l.). Remove the Allen key.
Make sure you hand-tighten the bolt with
the Allen key.
6.4
replacing the click-in brush ring
(Pages *18* and *19*)
The click-in brush ring on the backing pad cover
must be replaced (tool-free mounting and
removal) if it shows signs of wear or damage.
Remove the abrasive from the velcro backing
pad to replace the two-part click-in brush ring
assembly (6.2 Replacing the abrasive). Remove
one of the click-in brush ring parts by carefully
detaching it from the click-in hooks and repeat the
procedure for the second click-in brush ring part,
while holding the backing pad cover firmly in place
(1m. and 2m.).
Attach the new click-in brush ring parts in the
correct position, by clicking them carefully into the
click-in hooks provided (1n and 2n.).
You can now re-attach the abrasive
(5.3 Commissioning - section d. - images 1b.–3b.
on page *6*).
6. Maintenance and service
6.1 general information
The mains plug must be disconnected from the
mains socket before carrying out any work on the
device!
Do not use water or other liquid cleaning agents!
All parts of the housing
and operating
components and joints must
be cleaned regularly
with dry, clean compressed air, or with a fine
brush or dry, lint-free cloth!
Make sure that the ventilation slits
in the housing
are free and clean at all times!
Regularly clean the extraction zone underneath
the backing pad and the opening to the extractor
guide around the sanding disc with compressed
air, a fine brush or a dry, lint-free cloth.Check the
connection cable, mains plug and other machine
components regularly for visual damage and have
them replaced by your MENZER Service workshop
as needed!
All repairs on the device and any works that entail
opening any of the machine components must be
carried out by MENZER Service!
6.2 replacing the abrasive
(Page *15*)
Detach the worn abrasive from the backing pad
(1j.–3j. – page *15*) and press on the new abrasive
centrically in the same position (see page *6*).
The hook & loop layer will hold it in place. Ensure
correct alignment of the extraction openings and
select a grit size appropriate for the intended use
(see chapter 5.3 on commissioning).
Never use the power tool without an
abrasive attached. Sanding without an
abrasive would destroy the backing pad.
5.4 settings and handling
(Page *10*–*14*)
a. Switch on the industrial vacuum cleaner first,
and then the drywall sander. Hold the machine
securely and push the On/Off switch into position
I (A – see page *3*). Anticipate a spinning effect on
activation.
b. Grip the drywall sander firmly with both hands
positioned within the insulated grip areas (G1–G3)
(1f. – see page *10*). The additional handle (F)
can be mounted in various positions along the
machine pipes (2f. – see page *10*) to change the
operational range. Use the clip adapter provided
on the extension pipe.
The MENZER-LHS-225-VARIO
models allow the free adjustment of
the working length between 1,550 and 1,950 mm
(3f. – see page *11*). Loosen the locking nut (C – 4f
.
– see page *11*) until the telescopic extension pipe
(E VARIO) can be moved inwards or outwards (5f
.
– see page *11*). Set the desired working length
and tighten the locking nut (C) (6f. – see page *11*).
c. The rotational speed can be steplessly adjusted
as needed via the speed dial (B) (see page *3*).
Speed adjustments can be made during tool
operation. Higher speeds allow more abrasion,
while lower speeds ensure more control over the
sanding process.
Sanding performance, quantity and quality
depend largely on the correct choice of
abrasive.
d. Begin the sanding process by gently lowering
the device onto the substrate.
Press down with moderation to ensure that
the cup wheel lies flat and flush against the
substrate. Pressing down with too much force can
result in spiral-shaped scratch patterns on the
substrate and may damage the tool long-term. We
recommend using a circular, overlapping forward
motion of the sanding head across the work area.
The sander should remain in constant motion until
the desired refinement is achieved, as prolonged
sanding in place will result in abrasion marks.
Too much pressure will result in an overloading of
the machine and overheating of the sanding disc
and backing pad, leading to premature wear.
The sanding quality and performance depends
largely on the correct choice of abrasive.
e. Remove the detachable nose section
(1g.–3g. – see pages *12* and *13*).Press
down on the detachable nose section to unlock
the click-on connection on the backing pad cover.
Now you can disconnect the detachable nose
section on the left, then on the right from the
backing pad cover. Use the same work steps in
reverse to re-attach it (1h.–3h. – see pages *13*
and *14*).
f. Push the On/Off switch to position 0 (see page
*3*) to switch off. The backing pad with the
abrasive will slow down and come to a standstill.
Make sure that all movement has stopped before
putting down the machine.
caution! The mains plug must be
disconnected from the mains socket
and not be reconnected during any of the
described assemblies or disassemblies! Wait
until the backing pad has come to a complete
standstill!
