DANGER
Battery electrolyte contains sulfuric acid, which is
poisonous and can cause severe burns. Swallowing
electrolyte can be fatal or if it touches skin can
cause severe burns.
• Wear safety glasses to shield eyes, and rubber
gloves to protect skin and clothing when
handling electrolyte.
• Do Not swallow electrolyte.
• In the event of an accident, flush with water and
call a doctor immediately.
1. Check the voltage of the battery with a digital
voltmeter. Locate the voltage reading of the battery
in the table below and charge the battery for the
recommended time interval to bring the charge up
to a full charge of 12.6 volts or greater.
Important: Make sure the negative battery
cable is disconnected and the battery charger
used for charging the battery has an output of
16 volts and 7 amps or less to avoid damaging
the battery (see chart for recommended charger
settings).

moving parts could accidentally engage causing
personal injury.
Be sure ignition switch is in the "OFF" position
before charging the battery.

Note: If the positive cable is also disconnected,
connect the positive (red) cable to the positive
battery terminal first, then the negative (black) cable
to the negative battery terminal. Slip insulator boot
over the positive terminal.
Note: If time does not permit charging the battery,
or if charging equipment is not available, connect
the negative battery cables and run the vehicle
continuously for 20 to 30 minutes to sufficiently
charge the battery.
Installing the Side Bumpers
(Rear Discharge Units Only)
Mount the side bumpers in the top holes when operating
in height of cuts higher than 2 1/2 inches (64 mm) and
in the center holes when operating in height of cuts
lower than 2 1/2 inches (64 mm).
1. Raise the deck to the 5 inch (12.7 cm) height position
(also transport position).
2. Remove the bumpers from the sides of the crate.
1. Carriage bolt
2. Bumper
3. Move each bumper to the desired position and
secure with three 3/8–16 x 2 1/4 inch carriage bolts
and 3/8 inch nyloc nuts.
Positioning the Discharge Chute
(Side Discharge Units)
Loosen the two 3/8 inch nyloc nuts attaching the
discharge chute. Lower the discharge chute into
position. Retighten the nyloc nuts until the chute is snug
but can pivot freely.
