Assembly; Fitting The Cutting Head; Fitting The Bar And Chain; Fitting The Impact Guard - Husqvarna 525PT5S Operator's Manual

Fitting the cutting head

• Fit the cutting head on the shaft so that the screw (A)
is aligned with the hole in the shaft as shown.
B
• Tighten screw A.
• Tighten screw B.
CAUTION! Make sure that the drive shaft inside the shaft
engages with the cut-out in the cutting head.

Fitting the bar and chain

Unscrew the bar nut and remove the protective cover.
Fit the bar over the bar bolt. Place the bar in its rearmost
position. Place the chain over the drive sprocket and in
the groove on the bar. Begin on the top side of the bar.
Make sure that the edges of the cutting links are facing
forward on the top edge of the bar.
Fit the cover and locate the chain adjuster pin (A) in the
hole in the bar. Check that the drive links of the chain fit
correctly on the drive sprocket (B) and that the chain is in
the groove in the bar. Tighten the bar nut finger-tight.
A
Tension the chain by turning the chain tensioning screw
clockwise. Use a combination spanner or turn by hand.

ASSEMBLY

The chain should be tensioned until it fits snugly on the
underside of the bar.
• The chain is correctly tensioned when there is no
slack on the underside of the bar, and it can still be
turned easily by hand. Tighten the bar nut with the
combination spanner while holding up the tip of the
bar.
• When fitting a new chain, the chain tension has to be
checked frequently until the chain is run-in. Check the
chain tension regularly. A correctly tensioned chain
ensures good cutting performance and long life.

Fitting the impact guard

If the machine has a impact guard bolted under the
engine this should be removed before the impact guard is
assembled.
Fit the guard with three screws. Tighten the screws to 4
Nm. After the machine has been in use for around 20
hours, re-tighten the screws to 4 Nm.
