pulley slightly

COUNTERCLOCKWISE,

then

release

it to be sure the spring is properly

engaged with the pulley and that

the pulley

has good spring tension.

ROPE

INSTALLATION

Rope Purchase Instructions

The length

and diameter

of the starter

rope

required

will

vary

depending

on the

size

horsepower

engine

being

serviced.

Therefore,

check

the

Hand

Starter

Rope

Specifications

in the

Appendix,

and

then

purchase a quality nylon piece of the proper
length

and

diameter

size.

Only with

the

proper rope, will you be assured of

efficient

operation

following installation.

Each

end of the

nylon

rope

should

"fused" by burning them slightly with a very
small flame (a match

flame will do) to melt

the

fibers

together.

After

the

end fibers

have been "fused"

and while they

are

still

hot, use a piece of doth

as protection

and

pull the

end out

flat

prevent

a "glob"

from forming.

11-

Tie a figure g knot in one end of the

rope. Settheropeaside,

but handy, to be picked

up with one hand.

12-

Hold the housing with one hand and

rotate

the

pulley

three

complete

turns

COUNTERCLOCKWISE

with the other hand.

After three complete

turns have been made,

align the rope outlet

in the pulley with the

outlet

in the housing.

Insert

a drift

pin or

other

sui table

tool through

the

hole in the

pulley

and the

hole in the

housing

to hold

the pulley in the desired position.

Feed the

the rope through the pulley and the housing

and out the other

side of the housing.

Pull

the

rope

tight

until

the

knot

seated

against the pulley.

13-

A special

tool

is manufactured

OMC to install

the

handle

onto

the

rope.

This tool

has three

prongs

and is inserted

through the handle and then attached

to the

rope and pulled back through the handle.
