McCulloch 95390054000 Chainsaw User Manual


 
IMPORTANT ! make sure the chainsaw is not plugged
in before performing assembly or maintenance.
Assembly of bar and chain.
Remove the bar fastening knob (B1 in the
drawing), remove the pinion cover (10).
Install the chain on the bar as shown in the figure
B3, making sure the cutting edges are facing in the
direction of rotation (clockwise) see drwg. B2.
Install the bar in its housing and fasten the chain
on the pinion (B4 in the manual) taking care to fit
the adjustment tooth in the hole on the par (see
illustration B4 in the manual).
(B5) replace and partially tighten the bar fastening
knob without tightening it all the way.
B6-B7: adjust the tightener knob and increase the
tension so that when the chain is raised only the
guide tooth is visible (B6).
Make sure the chain glides smoothly in the bar
groove.
Tighten the bar fastener knob all the way (B1-B5).
NOTE to tighten the chain, turn clockwise; to
loosen it, turn counter-clockwise.
Important: excessive tightening of the chain will
shorten its life and that of the bar and motor.
B8: make sure the bar groove is free and clean.
Check the chain tension frequently during the
break-in period.

B. Instructions for assembly
Fill the tank with high quality chain lubricating oil.
Clean the tool to remove any oil that overflows. Do
not use solvents or liquid detergent.
Important: check the oil level regularly and top up
whenever it falls to less than a quarter. Do not use
waste oil or lubricants with characteristics that differ
from those indicated in this manual as this could
damage the tool NEVER USE THE CHAINSAW
WITHOUT OIL.
Your chainsaw is designed to function only when its
two handles are firmly gripped. To start the motor
press the trigger (8) and safety button (6)
simultaneously.
C. Instructions for use
Action of the chain brake
Further protection is provided by the safety chain
brake, that is operated with the left hand in case of
recoil. Contact with the brake lever causes
immediate stoppage of the chain.
See illustration D1 showing the high recoil risk zone
Chain brake lever system:
I= Machine on O= Machine off
D3 How to reset the chain brake after use:
Unplug the chainsaw and if the bar and chain are
blocked in the wood, release them before resetting
the brake.
To reset the brake pull the lever all the way back
keeping the trigger (8) released as shown in Fig. D3
Important! Check the chain tension before starting
the chainsaw again
D. Safety chain brake
Crosscutting logs
Fig. E1
Start the motor before the chain touches the log.
Hold the spike against the log and rotate the chain
slowly around the log.
Fig. E2
To crosscut a log resting on its ends: start cutting
from above to about 1/3 of the diameter, finish from
below using the top edge of the bar.
This will prevent the bar from being caught in the cut.
Caution: do not let the chain touch the ground.
Fig. E3
To crosscut a log on a sawhorse with at least one
free end, cut from above.

FELLING TREES
Important: a great deal of experience is needed to
fell a tree – operators lacking experience should
not fell trees
Important: we do not advise inexperienced loggers
to fell trees when the length of the bar is less than
the diameter of the tree
FELLING
Trees are felled with 3 cuts, first to direct the fall, by
cutting a notch consisting of a downward diagonal
cut, made first, followed by an upward diagonal cut
that should end exactly where the first cut ends
(see illustration alongside). The depth of the notch
should be equal to about 1/4 of the diameter of the
