NOTE:
It is recommended to use 2-3 chains alternatively.
In order to guarantee uniform wear of the guide bar the bar
should be turned over whenever replacing the chain.

6b. Only for the QuickSet guide bar

CAUTION:
Before doing any work on the guide bar or chain,
always switch off the engine and pull the plug
cap off the spark plug (see 7-6 "Replacing the spark
plug"). Always wear protective gloves!
CAUTION:
Start the chain saw only after having assembled it
completely and inspected.
On QuickSet guide bars the chain is tensioned using
a toothed rack in the bar. This simplifies retensioning
of the chain. These models do not have a conventional
chain tensioner. QuickSet guide bars are identified by
this symbol:

6b-1. Mounting the guide bar and saw chain

(Fig. 34)
Use the universal wrench delivered with the chain saw for the
following work.
Put the chain saw on a stable surface and carry out the
following steps for mounting the guide bar and saw chain:
Release the chain brake by pulling the hand guard (1) in
direction of arrow.
Unscrew retaining nuts (2).
Pull off the sprocket guard (3).
(Fig. 35)
Put the guide bar (4) on and push it against the sprocket (5).
(Fig. 36)
Lift the chain (6) over the sprocket (5).
Guide the chain from above about halfway into the groove (7)
on the guide bar.
CAUTION:
Note that the cutting edges along the top of the chain must
point in the direction of the arrow!
(Fig. 37)
Pull the chain (6) around the sprocket nose (8) of the guide
bar in the direction of the arrow.
(Fig. 38)
Replace the sprocket guard (3).

6a-4. Retightening the saw chain

(Fig. 33)
Loosen the nuts (2) about one turn with the universal
wrench.
Raise the tip of the guide bar a little and turn the chain
tensioning screw (4) to the right (clockwise) until the saw chain
is again up against the bottom edge of the guide bar (see
circle).
While keeping the tip of the guide bar raised, tighten the nuts
(2) again with the universal wrench.
IMPORTANT:
Lift the saw chain over the chain catcher (9).
Tighten the nuts (2) only hand-tight to begin with.

6b-2. Tensioning the saw chain

(Fig. 39)
Turn the QuickSet chain tensioner (10) to the right (clockwise)
using the combination tool, until the saw chain guide elements
engage in the guide groove on the bottom of the guide bar (if
necessary, pull the chain into position slightly).
Raise the tip of the guide bar slightly and turn the chain
tensioner (10) further until the saw chain is flush against the
bottom of the guide bar (see circle).
While still holding up the tip of the guide bar, tighten the
retaining nuts (2) with the universal wrench.
NOTE: If the guide bar has been turned over, turn the chain
tensioner to left (i.e. counter-clockwise) to tighten the chain.

6b-3. Checking the chain tension

(Fig. 40)
The tension of the chain is correct if the chain rests against the
bottom side of the guide bar and can still be easily turned by
hand.
While doing so the chain brake must be released.
Check the chain tension frequently - new chains tend to get
longer during use!
When checking the chain tension the engine must be switched
off.
NOTE: It is recommended to use 2-3 chains alternatively.
In order to guarantee uniform wear of the guide bar the bar
should be turned over whenever replacing the chain.

6b-4. Retensioning the saw chain

(Fig. 39)
Use the combination tool to loosen the fastening nuts (2)
about one turn. Raise the tip of the guide bar slightly and turn
the QuickSet chain tensioner (10) to the right (clockwise) until
the saw chain is again flush against the bottom of the guide
bar (see circle).
While still holding up the tip of the guide bar, tighten the
retaining nuts (2) with the universal wrench.
