CYLINDER COOLING FINS
Maintenance Interval: The cylinder cooling fins should be cleaned after every 25 hours of opera-
tion or once a week which ever comes first. Air must flow freely around and through the cylinder
cooling fins to prevent engine overheating. Leaves, grass, dirt and debris buildup on the fins will
increase the operating temperature of the engine which can reduce engine performance and short-
en engine life.
Maintenance: With the engine at ambient (room) temperature, loosen the cylinder cover screw
(knob) and lift off the cylinder cover. Clean all dirt and debris from the cooling fins and from around
the cylinder base. Reinstall the cylinder cover.
LUBRICA
TION : GEARCASE AND BLADES
The gearcase has a felt wick located at the blade opening. As the Hedge Trimmer is used, the
grease within gearcase becomes very soft. The recipro-
cating blades constantly draw small amounts of grease
between the blade contact surfaces for additional lubrica-
tion. If the gearcase is not lubricated at the recommended
intervals, a gearcase failure will occur due to a lack of
lubrication.
Gearcase failures due to improper maintenance are not covered by Maruyama warranty.
The gearcase and blades should be lubricated after each 10 hours of use.
NOTE: If the Hedge Trimmer is used under severe conditions such as high ambient temperatures
(above 25°C) or for extended continuous periods of operation, the gearcase and blades must be
lubricated every 2 hours.
Lubricate the gearcase at the grease fitting with a good quality #2 lithium-base grease. Lubricate
the blades using a light (#10 wt.) oil.
