CAUTION
leakage is evident, it is recommended that the grease be
checked once each year. Check grease level by loosening
the bolts in the differential case flanges and spreading
case halves. It is not necessary to totally disassemble the
case or remove the wheels for this inspection. Add Multi-
purpose Gear Grease such as Pennzoil No. 303 or
equivalent if necessary. Total grease capacity is 1-1/2
pounds (0.68 kg).
Do not use oil in the differential case
in place of grease–it will leak through
the seals.
ENGINE
Refer to the engine manual (separately furnished) for
proper lubrication and maintenance instructions.
MAINTENANCE
LUBRICATION
Lubricate the machine at the recommended locations and
intervals using the proper lubricants to ensure maximum
service and long life of your machine.
Lubrication locations must be free of dirt and grass
clippings and be well lubricated for proper operation.
The location and number of all lubricating points are listed
in the chart below. The type and frequency of lubrication
is specified. Use the following photos to locate the
lubrication points on the mower.
DIFFERENTIAL
Since the mower does not operate at high speeds, the
grease level in the differential is not critical providing that
there is sufficient grease to coat the gears. Unless
