Einhell GC-PT 2538 I AS [21/96] Cleaning maintenance and ordering of spare parts

8. Cleaning, maintenance and ordering

of spare parts

Always switch off the equipment and pull out the

spark boot plug before carrying out any maintenance

work.

8.1 Replacing the line spool / cutting line

1. Unscrew the retainer screw (Fig. 6a/Item G) in a

counter-clockwise direction and remove (Fig. 6b).

If you fail to do this by hand, use the key (Fig.

2/Item 10).

2. Remove the spool (Fig. 6c/Item H) and the spring

(Fig. 6c/Item I) from the spindle (Fig. 6c/Item J).

The following steps only have to be carried out if only

the line and not the entire spindle requires replacing:

n Remove the remaining cutting line from the spool.

n Hold the two halves of a new cutting line together

in the middle and place the loop in one of the

slots on the spool divider (Fig. 6d).

n Wind the line with tension in a counter-clockwise

direction as shown in the illustration (Fig. 6e), with

the two halves being separated by the spool

divider. Wind up all of the line down to the last

15cm of each end.

3. Fasten each of the ends of the line in a slot (Fig.

6f/Item L) on the opposite side of the spool.

4. Fit the springs on the inside of the spool and

thread each of the ends of the line through one of

the eyelets in the spool holder (Fig. 6c/Item K).

5. Insert the spool in the spool holder. Make sure

that the spring slides over the spindle and does

not get stuck.

6. Press the spool into the spool holder with your

hand and use your other hand to fasten the

retainer screw tightly (Fig. 6g).

7. Give each end of the line a strong tug to pull the

line out of the slots.

8. Cut off all excess line to reduce it to approx. 13

cm. This will reduce the load on the engine when

starting up and warming up.

8.2 Servicing the air filter

Soiled air filters reduce the engine output by supply

too little air to the carburetor. Regular checks are

therefore essential. The air filter (22) should be

checked after every 25 hours of use and cleaned if

necessary. If the air contains a lot of dust, the air filter

should be checked more frequently.

1. Remove the air filter cover (Fig. 10a).

2. Remove the air filter (Fig. 10b/10c)

3. Clean the air filter by tapping it or blowing it.

4. Assemble in reverse order.

Important: Never clean the air filter with petrol or

inflammable solvents.

8.3 Maintenance of the spark plug

Spark plug sparking gap = 0.6mm. Tighten the spark

plug with a torque of 12 to 15 Nm. Check the spark

plug for dirt and grime after 10 hours of operation and

if necessary clean it with a copper wire brush.

Thereafter service the spark plug after every 50 hours

of operation.

1. Pull out the spark plug boot.

2. Remove the spark plug (Fig. 11b) with the

supplied spark plug wrench (19).

3. Assemble in reverse order.

8.4 Grinding the safety hood blade

The safety hood blade (Fig. 7a/Item R) can become

blunt over time. When you notice this, undo the screw

holding the safety hood blade to the safety hood.

Clamp the blade in a vise. Sharpen the blade with a

flat file and make sure that the angle of the cutting

edge is not altered in the process. File in one

direction only.

8.5 Carburetor settings

Important. Settings on the carburetor may only be

made by authorized customer service personnel.

The air filter cover must be removed before any work

on the carburetor, as shown in Figures 10a and 10b.

Setting the throttle cable

If the maximum speed of the equipment falls over

time and you have ruled out all the other causes listed

in section 11 Troubleshooting, it may be necessary to

adjust the throttle cable.

First of all check whether the carburetor opens fully

when the throttle handle is pressed fully. This is the

case if the lever M impacts against the carburetor

housing when the throttle is fully open (Fig. 12a).

Figure 12a shows the correct setting. If the lever M

does not impact against the carburetor housing, it

must be adjusted.

The following work is required to adjust the throttle

cable:

n Undo the lock nut (Fig. 12b/Item N) a few turns.

n Undo the adjusting screw (Fig. 12b/Item O) until

the lever M impacts fully against the housing

when the throttle is fully activated, as shown in

Figure 12a.

n Retighten the lock nut.
