Step 6. Once the machine is in motion, remove
foot from the pedal. The mower will
now move ahead or to the rear, and the
use of the steering wheel will provide
directional control.
Step 7 .The mower is brought to a stop by
pressing your right foot against the brake
pedal and your left foot against the
clutch pedal. The drive belt will be
disengaged and the brake will be applied.
A
CAUTION
Gear changing should be done only
after the mower has been brought to
full stop. If the mower is not to be
used for a long period, place the
gear shift lever in NEUTRAL and
stop the engine. DO NOT leave the
machine on an incline.
OPERATING THE CUTTER BLADE
The cutting blades may be engaged while the
mower is moving or standing still. DO NOT
engage the cutting blades abruptly as the sudden
belt tension on the pulley may cause the engine to
stall.
t WARNING
t
When The blade drive is engaged,
keep feet and hands away from the
discharge opening and from the
blade.
To stop the blades, move the lift and
disengagement lever (figure 9) into the DISEN­
GAGED position. This raises the deck and
disengages the blades.
NOTE
When the machine is used for other
than mowing operations the blade
drive should be disengaged.
CRANKCASE OIL
To ensure maximum engine performance, perform
the following periodic maintenance:
Oil Check
Check the oil level in the crankcase before each
use of the machine and after every five hours of
operation. Oil should be kept between the add and
full marks on the dipstick.
After the first five hours of operating a new
engine, drain the oil (See figure 17.) from the
crankcase while engine is still hot and refill
crankcase with new oil; thereafter change the oil
every 25 hours of operation. This procedure
ensures for minimum wear of engine parts and
provides for virtually trouble-free operation. To
change the oil, proceed as follows;
Step 1. With the machine on level ground, place
a suitable metal container under the oil
drain plug, then remove the drain plug.
See figure 17.
Step 2. After the oil has been drained completely
from the crankcase, replace the drain
plug and tighten.
Step 3. Refill crankcase with 2V4 pints of good
quality, type MS, Engine oil into the
crankcase. Summer use SAE 30; Winter
(Below 40°F) use SAE 5W-20 or SAE
10W.
LUBRICATION
Lubricate the wheel bearings (2 per wheel) and the
upper and lower spindle bearings with SAE 30 oil
once a season. See figure 18.
