Bolens 138-784-401 - Manual (Page 15)

Minor carburetor adjustments may be required to
compensate for differences in fuei, temperature,
altitude and load.
Refer to separate engine manual
for carburetor adjustment information.
NOTE
A dirty air cleaner will cause an engine
to run rough. Be certain air cleaner is
clean and attached to the carburetor
before adjusting carburetor. Refer to the
separate engine manual.
LUBRICATION
STEERING GEARS
Wipe off the old grease and dirt. After every 25 hours
of operation place an automotive multi-purpose grease
in the teeth of the segment and pinion gears. See figure
15
.
FIGURE 15.
TRANSAXLE
Check the oil level four times a year. Lubricant should
be at the point of overflowing. Use SAE E.P. 90 oil.
Drain and refill every two years. Capacity 23/4 pints. See
figure 16.
LINKAGE
Once a season lubricate all the pivot points on the
clutch, brake and lift linkage with SAE 30 engine oil.
FRONT WHEELS
The front wheels are provided with grease fittings.
Lubricate at least once a season with automotive multi­
purpose grease.
PIVOT POINTS
Lubricate all pivot points with light oil at least once a
season.
BALL JOINTS
The ball joints and drag link ends are permanently
lubricated.
HYDROSTATIC OIL LEVEL
The transmission has been filled at the factory and
should not require changing for the life of the transmis­
sion. The following oils can be used: Texaco 2209,
General Motors Dexron B, Ford M2C-33F, Mobile Fluid
300, or a good quality SAE 20 High Detergent oil.
NOTE
Never use a multi-viscosity oil.
The transmission fluid level should be checked prior
to initial use. The level should not be above the COLD
mark which is about V 4 " from the bottom of the reser-
voir/expansion tank. See figure 17.
NOTE
Overfilling reduces the expansion area
in the reservoir/expansion tank and fluid
will spill at operating temperatures.
To check or add fluid to the transmission:
1. Unscrew the parking brake and relief valve knobs.
