Cleaning The Inside Of The Pinion; Safety And Maintenance Schedule - stayer OLMO G1-250 Operating Instructions Manual

All blades must be sharpened to the same angle, 30º.
Differing angles result in abrupt and irregular operation of
the saw chain, increase of the wear and will cause
breakage of the saw chain.
The front angle of 85º of the blade is the result of the cutting
depth of the rounded line. If a suitable file is used in a correct
manner, the correct front angle will be obtained
automatically (Fig. 49).
Files and how to work therewith (Fig. 50)
Use a special rounded file for saw chains (4 mm diameter)
to sharpen the saw chain. Standard rounded files are not
suitable for this work.
The file must only cut when pushed forward (arrow).
Raise the file when directing it backwards.
First sharpen the shortest blade. The length of this blade
will thus be the standard for all blades of the chain saw.
Always guide the file horizontally (90º with respect to the
guide bar).
The file support facilitates guiding the file. It is marked for
the correct 30º sharpening angle (keep marks parallel to the
saw chain when sharpening; refer to the illustration), and it
limits the correct cutting depth to 4/5 of the diameter of the
file. (Fig. 51)
After having sharpened the saw chain, the height of the
depth gauge must be checked with a chain calibrator.
Correct even the slightest excess height with a special flat
file (K).
Round the front of the depth gauge (L) (Fig. 52).

6.2 Cleaning the inside of the pinion (Fig. 53)
Before carrying out any work at the guide bar or saw
chain, always switch off the engine and extract the
spark plug cap (refer to "Replacing the spark plug").
Always wear protective gloves!
Never start the chain saw until it has been completely
assembled and checked.
Remove the pinion cover (10) (refer to section "SETUP")
and clean the inside with a brush. Remove the chain (5) and
the guide bar (6).
REMARK: Make sure that no residues or pollutants remain
in the slot of the oil guide and the tensor of the chain. To
replace the guide bar (6), chain (5) and pinion, refer to
"SETUP".
Cleaning the guide bar (6), lubricating the pinion nose
(Fig. 54)
You must wear protective gloves.
Regularly check the surfaces of the bearings of the guide
bar in order to see if they are damaged, and clean them with
a suitable tool.
Kind of pinion nose:
If the chain saw is being used intensively, it will be
necessary to lubricate the bearing of the return pinion
regularly (once a week). To do so, first clean thoroughly
clean the 2 mm hole of the guide bar (6), and the introduce a
small amount of multi-application grease.
The multi-application grease and the grease gun are
available as accessories.
Clean the outside, look if there are damages. Should there be damages, ask a qualified
Service Center to repair them immediately.
Sharpen it regularly; replace it at good time.
Ask a qualified Service Center to inspect it regularly.
Turn it around to make sure a uniform wear of the bearings. Replace it in good time.
Check to see if it is damaged and sharpened. Check the tension of the chain.
