MAINTENANCE

Tensioning the drive belt

The drive belt is fully enclosed and well protected from dust and dirt.

When tensioning the drive belt, slightly loosen the nuts (A) holding the cutting head and belt guard.

Turn the tension screw so that the nut (B) aligns with the arrow on the guard. Shake the head to ensure the spring can tension the belt. The belt now automatically has the right tension.

Tighten the nuts holding the cutting head.

IMPORTANT INFORMATION The tension of a new drive belt must be readjusted after one or two tanks of fuel have been used.

Replacing the drive belt

Loosen the two screws (A).

Turn the tension screw (B) until tensioning stops.

Remove the two screws (A).

Remove the front belt guard (C)

Remove the belt from the belt pulley.

Remove the cutting head.

Remove the screw (D). Remove the side cover.

Replace the drive belt.

Assemble in the reverse order as set out for dismantling.

Check that the blade guard over the cutting blade is not cracked or damaged in any other way. Replace when damaged.

WARNING! Never use the power cutter

!without a blade guard over the cutting blade.

Belt pulley and clutch

Never start the engine when the belt pulley and clutch are removed for maintenance.

Carburettor

Your Husqvarna product has been designed and manufactured to specifications that reduce harmful emissions. After the engine has used 8-10 tanks of fuel the engine will be run-in.To ensure that it continues to run at peak performance and to minimise harmful exhaust emissions after the running-in period, ask your dealer/service workshop (who will have a rev counter at their disposal) to adjust your carburettor.

Function

WARNING! Do not start the machine without

!the cutting arm or cutting head fitted. Otherwise the clutch could come loose and cause personal injuries.

The carburettor governs the engine speed via the throttle. Air and fuel are mixed in the carburettor.

Needles

The carburettor is equipped with fixed needles to ensure the machine always receives the correct mixture of fuel and air. When the engine lacks power or accelerates poorly, do the following:

Check the air filter and replace if necessary.

When this does not help, contact an authorised service workshop.

Fine adjustment of the idle speed T

Adjust the idle speed using the T screw. When an adjustment is necessary, first turn the screw clockwise until the blade starts to rotate. Now turn the screw anti-clockwise until the blade stops rotating. A correctly adjusted idle speed is set when the engine accelerates without hesitation.

Rec. idle speed: 2500 rpm

WARNING! If the idle speed cannot be

!adjusted so that the cutting attachment stops, contact your dealer/service workshop. Do not use the machine until it has been correctly adjusted or repaired.
