Maintenance - Scheppach PCS4-20ProS Original Bedienungsanleitung

Carry out the following work in the event of breaks in
operation lasting longer than 30 days:
• Oil the blades to prevent oxidation of the blades.
• Store the product between 10 °C and 30 °C. Avoid
extreme cold or heat during storage to prevent the
rechargeable battery from losing power.
• Do not store the product in a damp environment or
in places with corrosive gases, but in a dry place out
of the reach of children.
• During longer storage periods, check the charge
level of the rechargeable battery about every 3
months and recharge if necessary.
• Empty the oil tank for the saw chain oil.

12. Maintenance

Have maintenance and repair tasks that are not de-
scribed in this operating manual, carried out by our
specialist workshop. Use only original spare parts. Be-
fore all maintenance and cleaning tasks, let machine
cool down. There is a risk of burns!
m WARNING!
Danger of injury!
Use cut-resistant gloves when handling the saw chain
or guide bar.
- Switch off the motor before carrying out any clean-
ing or maintenance work.
- Remove the rechargeable battery.
12.1 Changing the guide bar (Fig. 2)
1. Switch the product off and remove the rechargea-
ble battery (15).
2. Place the product on a flat surface.
3. Turn the screw (2) for the chain tensioning system
and the chain cover (3) anti-clockwise to slacken
the chain tension and remove the chain cover (3).
4. Remove the guide bar (12) and the saw chain (11).
5. For dismantling, hold the guide bar (12) swivelled
upwards at an angle of approx. 45 degrees to
make it easier to remove the saw chain (11) from
the groove of the guide bar.
6. Replace the guide bar and fit the guide bar and
saw chain as described in "Fitting the guide bar
and saw chain".

12.2 Turning the guide bar (Fig. 2)
The guide bar (12) must be turned approximately
every 10 working hours in order to guarantee even
wear.
1. Switch the product off and remove the rechargea-
ble battery (15).
2. To do so, set the product down on a level surface.
3. Turn the screw (2) for the chain tensioning system
and the chain cover (3) anti-clockwise to remove
the chain cover (3).
4. Then remove the guide bar (12) and the saw chain
(11).
5. Rotate the guide bar (12) around its horizontal axis
and mount the guide bar and the saw chain as de-
scribed in "Fitting the saw chain and guide bar".
Observe the running direction of the saw chain!
6. To align the saw chain (11), follow the symbols
above the chain wheel (14) when turning the guide
bar (12). The running direction shown on the guide
bar is then no longer correct.
12.3 Changing the saw chain (Fig. 2)
m CAUTION:
- Only use saw chains and guide bars with guide bar
tips that are designed for this cordless pruning saw
(see extract from the spare parts list)!
- Before changing the saw chain, clean the groove
of the guide bar, as the saw chain may jump out
of the bar if it dirty (Fig. 9). The deposits can also
soak up the chain oil. The consequence would be
that the chain oil does not reach the underside of
the guide bar, or only to a small extent, and lubri-
cation is reduced.
1. Switch the product off and remove the rechargea-
ble battery (15).
2. To change the saw chain (11), place the product
on a flat surface.
3. Turn the screw (2) for the chain tensioning system
and the chain cover (3) anti-clockwise to remove
the chain cover (3).
4. First remove the guide bar (12) and the saw chain
(11).
5. Lay out the new saw chain (11) in a loop so that the
cutting edges are aligned clockwise. To align the
saw chain (11), follow the symbols (arrows) on the
guide bar or above the chain wheel (14).
6. Place the saw chain (11) in the groove of the guide
bar.
