MAINTENANCE & DISMOUNTING
WARNING
TO PREVENT INJURIES:
Stop the motor.
Apply parking brakes.
Remove the ignition key.
Disconnect the wire from the spark plug(s) and
keep away from spark plug(s) to prevent accidental
starting.
MAINTENANCE
a) Check mounting bolts at frequent intervals for
proper tightness to be sure the equipment is in
safe working condition.
b) Apply oil at all pivot points.
BELT ADJUSTMENT
When the attachment is on the ground, the tension
arm should be vertical or at approximately 90° with
the subframe’s flat bars.
If it is not vertical, release the tension on the belt by
moving the arm (item 1) towards the back. Adjust the
tension on the belt by moving the left hand side
adjustable pulley (item 3). To adjust, loosen the bolt
located in the middle of the pulley and slide the pulley
in the slot. Tighten the bolt. Apply tension on the belt
by moving the tension arm towards the front. Verify
the adjustment. Make sure the tension arm (item 2) is
approximately at 90° with the subframe’s flat bars and
blocked in the hole with a 3 mm hair pin.
c) Unhook the spring
d) Remove the two pins that hold the back of the
subframe.
e) Remove the two pins that hold the front of the
subframe.
f) Unhook and lower carefully the subframe.
g) Carefully pull out the subframe by middle of the
tractor from the left side between the front and
rear wheels.
END OF SEASON STORAGE
a) Clean and repaint all parts from which the paint
has worn.
b) Apply oil at all pivot points.
c) Inspect and replace all defective parts before next
season.
CAUTION
TO PREVENT INJURIES:
Always raise the attachment to reduce the
tension on the spring before applying or
releasing tension on the helper spring. Firmly
hold the handle when you release the tension
because the arm will kick back due to the tension
on the spring.
SUBFRAME DISMOUNTING

Rotary Broom, Utility Blade) for attachment
dismounting instructions.
