Maintenance Interval
The gearcase and angle drive should be inspect after
each IO to
20
hours of use.
Cutting blades should be lubricated at all times.
Lubrication
The gearcase has a felt wick locataed at the blade
openmg. As the Hedge trimmer is used, the
grease within gearcase becomes very soft.
The reciprocating blades constantly draw small
amounts of grase between the blade contact
surfaces for additional lubrication.
If the gearcase is not lublicated at the re
commened intervals, a gearcase failure will occur
due to a lack of lubrication.
Gearcase failures due to improper maintenance is
not covered by MARUYAMA warranty.
The gearcase and blades should be lubricated after
each 10 hours or use.
NOTE: If the Hedge Trimmer is used under severe
conditions such as high ambient temperatures
(above 75
°
F) 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 litium-base grease. Lubricate the
blades using a light (#10 wt.) oil.
