Maintenance - Stiga CS 48 Li 14 Operator's Manual

– Do not let the chain contact the ground.
After completing the cut, wait for the
saw chain to stop before you move
the chain saw. Always stop the motor
before moving from tree to tree.

6. MAINTENANCE

Always remove the battery pack from
the machine before checking the chain
tension or making adjustments to the
chain. Wear protective gloves while touching
the chain, bar or areas around the chain.
ADJUSTING THE CHAIN TENSION
See figure 2
• Un-tighten the sprocket cover
tighten knob (item 15) slightly by
turning it counterclockwise.
• To increase the chain tension, turn the
chain tensioner adjustment knob (item
13) clockwise and check thechain tension
frequently. To reduce the chain tension,
turn the chain tensioner adjustment
knob (item 13) counterclockwise and
check the chain tension frequently.
• The chain tension is correct when the gap
between the cutter in the chain and the bar
is between 3mm-4mm. Pull the chain in the
middle of the lower side of the bar downwards
(away from the bar) and measure the distance
between the bar and the chain cutters.
• Tighten the sprocket cover tighten knob
(item 15) by turning it clockwise.
REPLACING THE BAR AND CHAIN
See Figure 2, 3, 5, 7
• Put the saw down on a flat and even surface
to make adjustments to the chain.
• Make sure that you have the correct
replacement bar and chain as advised earlier
in the specification section of this manual.
• Unscrew the sprocket cover tighten knob
(item 15) by turning it counterclockwise until
the sprocket cover (item 14) comes loose.
• Remove the sprocket cover. Remove
the bar and saw chain from unit.
• To replace the bar with the new one, unscrew
the nut of the safety tip, mount the safety
tip on to the new bar and tighten the nut.
• Put the new chain in the correct direction
as shown in figure 7 onto the bar and
make sure that the drive links are
aligned in the bar groove (figure 5).
• Attach the bar to the chain saw and
loop the chain around the drive
sprocket as shown in figure 3.
• Replace the sprocket cover (item 14), tighten
sprocket cover and tighten knob (item 15).
• Follow the steps the section "ADJUSTING
THE CHAIN TENSION" earlier in this manual.
ADDING CHAIN & BAR LUBRICANT
• Unscrew and remove the cap
(item 6) from the oil tank.
• Pour the oil into the oil tank and monitor the
oil level gauge (item 7). Ensure that no dirt
enters the oil tank while filling the oil in.
• Put the oil cap back on and tighten it up.
• One full oil tank will enable you to
use the saw for 20- 40 min.
TRANSPORTING THE CHAIN SAW
Before transporting the chain saw, always
remove the battery pack from the chain saw and
slide the chain cover over the bar and chain. If
several cuts are to be performed with the chain
saw, the saw must be switch off between cuts.
GUIDE BAR COVER
see figure 1
The chain cover must be clipped onto
the chain and bar as soon as the sawing
work has been completed and whenever
the machine has to be transported.
SHARPENING THE SAW CHAIN
See figure 16 - 21
When the chain penetrates into wood with
difficulty, it needs sharpening as follows:
• Put the chain under tension.
• Fasten the bar in a vice so that
the chain can slide.
• Fasten the file to the file holder and
place it on cutter at 35° angle.
• File with forward strokes only until all the worn
out parts of the cutting edge are taken away.
• Count the number of strokes given to the
cutter as a reference and file away with the
same number of strokes on all other cutters.
• If the depth gauge protrudes from
the template after sharpening a few
times, reset its level. Use a flat file.
Finally, round off the depth gauge.
NOTE: It is recommended to have
the deep or important
sharpening carried out by a service agent
who is equipped with electric sharpener.
GUIDE BAR MAINTENANCE
• When you have finished working,
clean out the groove and the oil
passages with a scraping hook.
• Periodically trim the sides of rails using a flat
file. If not done in the long run, the feather
edges might break away and damage the bar.
• If one rail is higher than the other
one, it is necessary to make it even
