50-hour Maintenance

Every 50 hours of operation

(more frequently in dusty or dirty

conditions):

Remove and clean the cylinder cover

and clean grass and dirt from the cylin-

der fins.

Remove the cutting attachment, cutting

attachment holder and gear shaft collar.

Remove the filler plug from the side of

the gear case and press new grease into

the gear case until old grease is pushed

out. Use only lithium-base grease such

as Shindaiwa Gear Case Lubricant or

equivalent. See Figure 30.

Lubricate main shaft splines.

Use a hooked wire to extract the fuel

filter from inside the fuel tank.

See Figure 31.

CAUTION!
Make sure you do not pierce the fuel

line with the end of the hooked wire.

The line is delicate and can be dam-

aged easily.

Every 10 to 15 hours

of operation:

Remove and clean the spark plug. Adjust

the spark plug electrode gap to 0.024 - 0.028

inch (0.6 - 0.7 mm). If the spark plug must

be replaced, use only an NGK CMR5H or

equivalent resistor type spark plug of the

correct heat range. See Figure 29.

CAUTION!
Before removing the spark plug, clean

the area around the plug to prevent

dirt and debris from getting into the

engine’s internal parts.

Clean the spark plug

and check the gap at

the electrode.

NOTE:

The NGK CMR5H also meets the require-

ments for electro magnetic compliance

(EMC).

Remove and replace the filter element.

Before reinstalling the new filter element,

inspect the condition of all the fuel system

components (fuel pick-up line, fuel return

line, tank vent line, tank vent, fuel cap and

fuel tank). If damage, splitting or deteriora-

tion is noted, the unit should be removed

from service until it can be inspected or

repaired by a Shindaiwa-trained service

technician.
