WARNING: Use only the cable screw that came with the engine brake cable. Ifthe cable screw has been lost, get a new one from a Sears, Roebuck and Co. (or Sears Canada, Inc.) Service Center. Any cable screw used must be the same length as the original cable screw. STARTER ROPE:

A. Depress mower control bar (see Figure 3) against mower

handle and hold it in this position.

B. Pull at least 2 feet of starter rope out of starter and tie a slip

knotat starterto prevent starter rope from rewinding back into

starter.

C. Slide rope stop (see Figure 2) onto starter rope and feed

starter rope through rope guide on mower handle, (see

Figure 4).

D. Feed starter robe through starter handle (see Figure 5) and

tie a left hand knot, leevingl/2 inch to 1 inch of starter rope

extending beyond knot. DO NOT PULL LEFT HAND KNOT INTO STARTER HANDLE YET.

E. With starter handle resting on rope guide (see Figure.4),

check starter rope for slack. If there is any slack, pull more starter rope through starter handle and relocate left hand knot to eliminate slack.

F. Untie slip knot at starter. G. Pull left hand knot into starter handle.

H. Position rope stop 2 to 3 inches from starter (see Figure 2)

and fasten it to starter rope by gripping it with pliers and

forcing staple through starter rope untilstaple is even without

_) side of robe stop.

CHECK OIL LEVEL:

CAUTION: NEVER RUN ENGINE UNLESS OIL LEVEL IS BE- TWEEN "FULL" AND "ADD" MARKS ON DIPSTICK, CHECK OIL LEVEL OFTEN DURING ENGINE BREAK-IN, NEVER RUN ENGINE UNLESS OIL FILL PLUG IS TIGHTENED SECURELY INTO OIL FILL HOLE,

A. POSITION EQUIPMENT SO ENGINE IS LEVEL. B. Clean area around oil fill plug (see Figure 1). •

C. Remove oil fill plug and dipstick.

D. Wipe dipstick clean, insert it into oil fill hole and tighten

securely.

E. Remove oil fill plug :_ndcheck oil level. If level is not up to

"FULL" mark on dipstick, add recommended oil, until it is. POUR SLOWLY. Wipe dipstick clean each time oil level is checked. DO NOT FILL ABOVE =FULL" MARK ON DIP- STICK.
