Maintenance Instructions - Virutex RM95R Gebrauchsanweisung

Always ensure that the saw is not in contact with the frame
before activating the on/off switch.
Move the machine along the guides, pressing on the handle, until you
reach the end, and fix in this position using knob "V" (Fig. 13). The
initial contact when cutting the frame should be done gently, without
brusque movements or excess pressure.
Introduce the crank lever once again and, holding it firmly, cut vertically,
turning the crank lever anti-clockwise until you have finished.
The machine has a mechanical safety clutch that slips and prevents
you from continuing if too much effort is required for cutting, either
due to deterioration of the chain or to advancing too fast.
The crank lever returns automatically to its free turning position when
it stops being pressed towards the inside. This means that a forward
and back motion can be used at the beginning and end of the cut,
when the lever comes into contact with the floor or ceiling and cannot
turn completely. This mechanism also prevents the lever from turning
and hitting the user when the machine is being moved downwards at
the end of a cutting action.
Once the frame has been cut, loosen the knob "V" (Fig. 13) to release
the machine from the cut and return it to its rest position. Let go of
the switch to stop the motor.
Release the catch "C" (Fig. 2) and slide the machine along the guide to
a lower position, remove the machine from the stand.
Close the oil control "S" (Fig. 14) if the machine is going to be turned
off for more than an hour.
Disconnect the machine from the mains before removing
it from the stand.
11. CHANGING THE CHAIN OR THE GUIDE BAR
Change the chain when cutting becomes difficult.
Do not wait until it is completely used up.Disconnect the ma-
chine from the mains before performing any operation.
Wear leather gloves in your own size when carrying out
this operation.
To change the chain or the guide bar, in the event it is either broken
or shows signs of normal wear and tear, proceed as follows:
Loosen screw W (Fig. 16) and open the cover "Z" that protects the
saw.
Remove the screws "X" (Fig. 16) and the fixing plate "Y" and, using
extreme caution, take off the guide bar and the chain. To do this, pull
back the guide bar and remove the chain from the driving pinion.
Check the condition of the bar before putting on a new chain.
Replace the bar if it is bent, damaged or if the guide
channel is gaping.
Before putting on a new chain, it is a good idea to first bathe it in oil.
This will prolong its working life.
Next, place the new chain inside the bar guide and attach the whole
lot to the machine, hinging the chain links on the driving pinion of
the motor. Tighten the chain by hand only and attach the fixing plate
using its own screws.
Close the cover "Z" (Fig. 16) and fix it in place using screw W.
After replacing a guide bar or a chain, it is a good idea to run the
machine for 2 or 3 minutes unloaded and to lubricate well before
beginning to cut.
When you have made a couple of cuts with the new chain, check that
it is correctly tightened and retighten, if necessary.
Never turn the machine on with the protection cover
open.
Do not use a screwdriver or similar object as a lever to
tighten the chain. This would cause the tool to overheat
and the chain to break.
Ensure that the chain is fitted correctly within its guide and
that the bar is properly attached to the machine.

12. MAINTENANCE INSTRUCTIONS

Disconnect the machine from the mains before performing
any operation.
LUBRICATION AND CLEANING
The machine has a lubrication system to prevent it from becoming
clogged up by wood shavings when being used for long periods at
a time. However, if you discover that the oil outlet tube is clogged,
proceed as follows:
If the obstruction is small, activate the valve several times to release
the sawdust plug. If the obstruction persists, remove the chain and
the guide bar and unscrew the nozzle "A1" (Fig. 17) and clean it with
a fine needle. To ensure that the distribution tube is perfectly clean,
remove the oil tube "B1" (Fig. 16) from the nozzle and blow through it
with a dry air compressor. Return the nozzle to its position and check
that the oil is flowing through the outlet tube before replacing the
guide bar and the chain.
Lubricate the front pinion of the guide bar every day by putting a few
drops of oil into the hole "C1" (Fig. 16).
Keep the bar rail clean and free from splinters, resinous wood shavings,
etc. If necessary, the bar can be removed from the machine so that
the rail can be cleaned with a knife or sharp tool.
MECHANICAL PARTS
After many hours of operation, it is possible that the driving pinion
"K1" (Fig. 17). may wear out. To replace it with a new one, open the
protective cover and take off the chain and the guide bar as explained
in the section for changing the chain. Hold the fixing plate "D1" (Fig.
17) with the service key and remove the screw "E1" (Fig. 17) that holds
it in place. Replace the broken or worn pinion with a new one and
return all of the components to their original positions.
TIGHTNESS
The oil that lubricates the rail of the guide bar passes through a hole
in the guide bar that is completely tight, thanks to a seal "F1" (Fig. 17).
If the condition of the seal deteriorates, it must be changed to prevent
oil leakages or insufficient lubrication of the chain.
13. ATTACHING THE DUST COLLECTOR
The dust collector connection "G1" (Fig. 13) can be connected directly
to the tube of the dust collectors AS182K and AS282K, or else the
standard 3.5 m dust collector attachment, 6446073, can be used.
14. CHANGING BRUSHES
Make sure the machine is disconnected from the mains
before performing any operation.
Brushes should be changed when they have a minimum length of 5
mm. To do this, remove the covers "H1" (Fig. 15) that hold the brushes
"J1" in place and replace them with new VIRUTEX original brushes,
making sure that they slide smoothly inside the guides.
It is advisable to allow the machine to run for 15 minutes unloaded
after changing the brushes. When changing the brushes, check the
condition of the collector. If it is burnt or juts out, it should be serviced
by a Virutex service technician.
15. NOISE AND VIBRATION LEVELS
The noise and vibration levels of this electrical tool have been mea-
sured in accordance with standard UNE-EN 60745-1 (measurements
taken in a vacuum)
The noise level in the workplace could go over 85 dB (A). In this case
the user should wear noise protection.
16 GUARANTEE
