KNIFE - PITMAN

Grease pitman and knife after every hour of op-

eration. However, when mowing in sandy or

gritty conditions it may be better to leave the

knife run dry. The knife should be sharpened

as often as necessary to maintain a good cut-

ting edge. Keep the knife straight and true;

any slight bend should be straightened.

Lubricate wear plates

and

knife clips with oil

or grease every one or

two

hours of steady op-

eration.

DO NOT ATTEMPT TO LUBRICATE WHILE

MOWER IS IN OPERATION.

CAUTION: Run engine at reduced speed when-

ever possible to reduce vibration and wear on

pitman and knife. Operating angle of cutter bar

not to exceed 35'above level.

It is the responsibility of the operator to see

that the area where the sickle bar will be used

is free of all types of foreign material. This

includes wire, rope, sticks, cans, bottles,,

pipe, rocks, etc. These represent potential

dangers to the sickle bar and operator, and are

certain to damage the sickle bar.

Always be on the alert for obstacles when

mo-

wing,

and never leave the

sickle

bar in oper-

ation

while unattended.

NOTE: Sickle bar must be in operation before

beginning to move through material to be

cut.
