STEP 6: Set-up is now complete for push models

without self-propelled drive system. For self-propelled
models continue to the “Self-Propelle d Models” Sectio n.
Proceed to the Pre Sale Checklist section of this
instruction to prepare mower for use.

SELF-PROPELLED MODELS

NOTE: The set-up procedure for self-propelled models is

basically the same as the Push Models. Follow the exact
procedure as described in Steps 1 thru 6 from the Push
Models section.

STEP 7: Check the cleara nce between the clutch cable
and clutch spring. NOTE: Clearanc e betwee n spring and
cable is very im portant. Excessive clearance will c ause
drive system NOT to oper ate when wheel drive control
handle is depressed. No clearance at all will cause
mower to continue to propel itself when wheel drive
control handle is released to stop mower movement.
Slide vinyl spring cover (located at the end of clutch
cable) up clutch cable to gain access to the end of spring
and cable loop. With wheel drive control handle
released, clearanc e bet ween spri ng hook and cab le loop
should be 1/16” to 1/8”. If cleara nce is m ore or less than
specified, unhook spring from clutch cable eye, then
adjust by rotating outer spring clockwise or counter
clockwise to achieve the proper clearance. Rehook
spring to clutch cable eye. Slide vinyl cover over the
spring when correct clearance is reached. See Figure 6.
