Cutter Blade Adjustment

WARNING!

The cutter blades are very

sharp! Always wear gloves when

working around the cutter assembly.

CAUTION!

Operating the trimmer with worn or

improperly adjusted cutters will reduce

cutter performance and may also

damage your unit.

Cutter performance of your unit depends

in great measure on cutter blade clearance.

Properly adjusted blades will oscillate

freely yet help prevent binding of cut

material between blades. Adjust blades as

follows:

1. Loosen all blade locknuts at least one

full turn.

2. Tighten each blade shoulder bolt ﬁrmly,

and then loosen the shoulder bolts 1/4

to 1/2 turn.

3. Working from the gearcase end, lock

each bolt in place by ﬁrmly tightening

its locknut while preventing the

shoulder bolt from turning.

When shoulder bolt adjustment is correct,

there should be a gap of 0.25–0.50 mm

between the cutter blades and the ﬂat

washers, and the ﬂat washer beneath each

bolt head should turn freely.

Long Term Storage

Whenever the unit will not be used for

30 days or longer, use the following

procedures to prepare it for storage:

 Clean external parts thoroughly and

apply a light coating of oil to all metal

surfaces.

 Drain all the fuel from the fuel tank.

IMPORTANT!

All stored fuels should be stabilized with a

fuel stabilizer such as STA-BIL™.

To remove the remaining fuel from the

fuel lines and carburetor and with the fuel

drained from the fuel tank.

1. Prime the primer bulb until no more fuel

is passing through.

2. Start and run the engine until stops

running.

3. Repeat steps 1 and 2 until the engine will

no longer start.

CAUTION!

Gasoline stored in the carburetor

for extended periods can cause

hard starting, and could also lead to

increased service and maintenance

costs.

 Remove the spark plug and pour about

3 ml of 2-cycle mixing oil into the

cylinder through the spark plug hole.

Slowly pull the recoil starter 2 or 3

times so oil will evenly coat the interior

of the engine. Reinstall the spark plug.

 Before storing the unit, repair or replace

any worn or damaged parts.

 Remove the air cleaner element from the

carburetor and clean it thoroughly with

soap and water. Let dry and reassemble

the element.

 Store the unit in a clean, dust-free area.
