tain that all loose parts and literature are removed from
carton before carton is discarded.
2. Extend throttle control assembly, which is attached to en
gine, to rear of mower and place on floor, CAUTION; Do
not bend or kink control wire.
3. Assemble upper handle to lower handle using four each
screws and lock nuts provided in parts bag.
4. Assemble complete handle assembly to mower so that
throttle control mounting hole in upper handle will be on
right side. Holes at bottom of lower handle are to be
fitted over studs located in front of each rear wheel
mounting position.
5. Position throttle control assembly on right hand side of
upper handle so that holes in control assembly and handle
are in line. Secure in place with screw and lock nut found

OPERATION
1. Service engine with gas and oil. See engine manual pack
ed with lawn mower for complete instructions for the care
and maintenance of engine. READ DIRECTIONS CARE
FULLY.
2. When ready to start engine, place throttle control lever, on
handle, in “START” position and start engine in accord
ance with instructions in engine manual. After engine
starts, move throttle control lever, on handle, to desired
engine speed. The engine is stopped by placing control
lever on handle in the “STOP” position.
3. Be sure that lawn is cleat of stones, sticks, wire or other
objects which could damage lawn mower or engine. For
best results and to insure more even grass distribution, do
not mow when lawn is excessively wet.
ADJUSTMENTS
CAUTION; Do not at any time make any adjustment to lawn
mower without first stopping engine and disconnecting spark
plug wire.
CUTTING HEIGHT - An adjusting plate and thumb lever at
each wheel position provides cutting height adjustment.
Each adjusting plate has five holes. Heigjit of cut will be
changed when the thumb lever is moved from one hole to
another. Simply depress thumb lever towards wheel and move
wheel and lever assembly to desired position. Cutting
height will be raised as lever is moved toward front and
lowered as lever is moved toward rear. All wheels must be
positioned in relative height of cut positions.
THROTTLE - If adjustment becomes necessary, the throttle
control wire assembly can be reset as follows;
1. Loosen, but do not remove, screw securing throttle control
wire assembly at engine.
2. Move throttle control lever on handle to “FAST” position.
3. Move lever, to which control wire is fastened at engine,
to full open position and retighten screw to secure
throttle control wire assembly.
FORM NO. 770-2394D
IMPORTANT: Always stop engine and disconnect spark plug
wire before cleaning, lubricating or doing any kind of
work on lawn mower.
WHEELS - Wheel bearings are of lifetime Fortiflex. They
require no lubrication.
THROTTLE - Periodically lubricate throttle control lever
and throttle wire assembly with a few drops of light oil
(S.A.E. No. 10 or 20), for ease of operation.
ENGINE - Follow engine manual for lubrication instructions.
MAINTENANCE
CUTTING BLADE - The blade may easily be removed for
grinding or replacement as follows;
1. Remove bolt and lock washer holding blade and hub as
sembly to engine crankshaft.
2. Remove blade and hub assembly from engine crankshaft.
3. Remove two bolts,lock washers and nuts holding blade
to blade hub.
When sharpening blade, follow the original angle of grind as
a guide. It is extremely important that each cutting edge re
ceives an equal amount of grinding to prevent an unbalanced
blade. An unbalanced blade will cause excessive vibration
when rotating at high speeds and may cause damage to the
mower.
Upon reassembly, make certain all parts are assembled
properly and tightened securely.
DECK - The underside of mower deck should be cleaned
after each period of use as grass clippings, leaves, dirt and
other matter will accumulate. This accumulation of grass
clippings, etc., is undesirable as it will invite rust and cor
rosion and may cause an uneven discharge of grass clippings
at the next cutting.
The deck may be cleaned by tilting the mower forward or on
its left side and scraping clean with a suitable tool or by
washing with a stream of water from a garden hose. CAU
TION; Do not direct the stream of water at a hot engine as
damage to the engine may result.
STORAGE - The following steps should be taken to prepare
lawn mower for storage.
1. Clean and lubricate mower thoroughly as described in the
preceding instructions.
2. Refer to engine manual for correct engine storage instruc
tions.
3. Coat mower’s cutting blade with chassis grease to pre
vent rusting.
4. Place blocks under deck to raise tires clear of floor.
5. Store mower in a dry, clean area.
USING YOUR ROTARY MOWER
For best results do not cut wet grass because it tends to
stick to the utiderside of the mower thus preventing proper
discharge of grass clippings. If wet grass must be cut, re
duce engine speed and walking speed to help distribute the
clippings more effectively.
New grass should be treated as wet grass, otherwise a nor
mal walking speed is about the right pace for efficient
mowing.
The best mowing pattern is one that allows the clippings to
discharge towards the uncut part of the lawn. This permits
recutting of the clippings to further pulverize them. When
cutting high weeds, discharge towards cut portion then recut
at right angles to first direction.
Lawn should be cut in the fall as long as there is growth.
