Cold start

For machine with Loop Handle
– Push the I-O switch (1) in the direction shown by the arrow.	(1)

–First place the machine on the ground.

–Give a gentle push on the primer pump (1) repeatedly (7-10 times) until fuel comes into the primer pump.

–Push the choke button (2) to the position " "

– Firmly hold the clutch case by your left hand, as illustrated.	(2)
	(1)

–Slowly pull the starter grip until resistance is felt and continue with a smart pull.

– Do not pull out the starter rope to its full extent and do not allow the starter handle to be retracted without control, but ensure that it is retracted slowly.

– Repeat the starting operation until initial ignitions are heard.

–When the engine starts, please open the throttle lever a little. The choke button being automatic, it returns to original position " ".

–Run the engine for approximately one minute at a moderate speed before applying full throttle.

12

Note: – If the starter knob is pulled repeatedly when the choke button remains at “ ” position, the engine will not start easily due to excessive fuel intake.

–In case of excessive fuel intake, remove the spark plug and pull the starter knob slowly to remove excess fuel. Also, dry the electrode section of the spark plug.

Caution during operation:

If the control lever is opened fully in a no-load operation, the engine rotation is increased to 10,000 rpm or more. Never operate the engine at a higher speed than required and at an approximate speed of 6,000 - 8,000 / min.

Starting the warm engine

– As described above, except without moving the choke button.

Stopping

–Release the throttle lever (6) fully, and when the engine rpm has lowered, push the I-O switch (1) to “O” position the engine will now stop.

–Be aware that the cutting head may not stop immediately and allow it to slow down fully.

IDLE ADJUSTMENT

The nylon cutting head should not run when the control lever is fully released. If necessary, adjust the idle rpm using the idle adjusting screw.

Checking the Idling speed

(1)

–Idle speed should be set to 3,000 / min.

If necessary correct it by means of the idle screw (the nylon cutting head must not turn when the engine is on idle).

Screwing in the screw (1) will cause an increase in the engine speed, whereas backing off the screw will reduce the engine speed.

Slow High

NYLON CUTTING HEAD

The nylon cutting head is a dual string trimmer head capable of bump & feed mechanisms.

The nylon cutting head will automatically feed out the proper length of nylon cord by the changes in centrifugal force caused by increasing or decreasing RPMS. However, to cut soft grass more efficiently, bump the nylon cutting head against the ground to feed out extra cord as indicated under operation section.

Most effective cutting area

Operation

–Increase the nylon cutting head speed to approx. 6,000 / min.

Low speed (under 4,800 / min) is not suitable, the nylon cord will not feed out properly at low speed.

–The most effective cutting area is shown by the shaded area.

13

If the nylon cord does not feed out proceed as follows:

1.Release the control lever to run the engine idle and then squeeze the control lever fully. Repeat this procedure until the nylon cord feeds out to the proper length.

2.If the nylon cord is too short to feed out automatically with the above procedure, bump the knob of the nylon cutting head against the ground to feed out the nylon cord.

3.If the nylon cord does not feed out with procedure 2, rewind/replace the nylon cord by following the procedures described under “Replacing the nylon cord”.

Replacing the nylon cord

–First, stop the engine.

–Press on the housing latches inward to lift off the cover, then remove the spool.

–Hook the center of new nylon cord into the notch in the center of the spool, with one end of the cord extending about 80mm (3-1/8") more than the other. Then wind both ends firmly around the spool in the direction of the head rotation (left-hand direction indicated by LH and right-hand direction by RH on the side of the spool).

–Wind all but about 100mm (3-15/16") of the cords, leaving the ends temporarily hooked through a notch on the side of the spool.

–Mount the spool in the housing so that the grooves and protrusions on the spool match up with those in the housing. Keep the side with letters on the spool visible on the top. Now, unhook the ends of the cord from their temporary position and feed the cords through the eyelets to come out of the housing.

–Before operation, always check for clogging of the cooling air passage and the cylinder fins. Clean them if necessary.

–Perform the following work daily after use:

•Clean the string trimmer externally and inspect for damage.

•Clean the air filter. When working under extremely dusty conditions, clean the filter the several times a day.

•Check the nylon cutting head for damage and make sure it is firmly mounted.

•Check that there is sufficient difference between idling and engagement speed to ensure that the nylon cutting head is at a standstill while the engine is idling (if necessary, reduce idling speed).

If under idling conditions the tool should still continue to run, consult your nearest Authorized Service Agent.

–Check the functioning of the I-O switch, the lock-off lever, the control lever, and the look button.

Cleaning of air cleaner

Clogging of the element (1) may sometimes make it difficult or impossible to start up the engine or increase the engine speed.

After the end of operation, be sure to clean the air cleaner as mentioned below.

– Remove the air cleaner cover screw.
– Place the finger under the air cleaner cover, push down the cover lower
part, and detach the air cleaner cover.	(1)
– Take out the element (1), clean it with lukewarm water mixed with neutral
detergent, and dry it completely.	(2)

NOTE:If there is excessive dust or dirt adhering to the air cleaner, clean it every day. A clogged air cleaner may make it difficult or impossible to start the engine or increase the engine rotational speed.

15

Checking the spark plug

–Only use the supplied universal wrench to remove or to install the spark plug.

–The gap between the two electrodes of the spark plug should be 0.6 - 0.7 mm (0.024" - 0.028"). If the gap is too wide or too narrow, adjust it. If the spark plug is clogged with carbon or fouled, clean it thoroughly or replace it.

CAUTION: Never touch the spark plug connector while the engine is running (danger of high voltage electric shock).

Supply of grease to gear case

–Supply grease (Shell Alvania 3 or equivalent) to the gear case through the grease hole every 30 hours. (Genuine DOLMAR grease may be purchased from your DOLMAR dealer.)

Suction head in the fuel tank

– The felt filler (1) of the suction head is used to filler the fuel required by the
carburetor.
– A periodical visual inspection of the felt filter is to be conducted. For that
purpose open the tank cap, use a wire hook and pull out the suction head
through the tank opening. Filters found to have hardened, been polluted or
clogged up are to be replaced.
– Insufficient fuel supply can result in the admissible maximum speed being
exceeded. It is therefore important to replace the felt filter at least quarterly
to ensure satisfactory fuel supply to the carburetor.	(1)

Cleaning of muffler exhaust port
