Danger
Under certain conditions, diesel fuel and fuel
vapors are highly flammable and explosive. A fire
or explosion from fuel can burn you and others
and can cause property damage.
• Use a funnel and fill the fuel tank outdoors, in
an open area, when the engine is off and is cold.
Wipe up any fuel that spills.
• Do not fill the fuel tank completely full. Add fuel
to the fuel tank until the level is 1 in. (25 mm)
below the bottom of the filler neck. This empty
space in the tank allows the fuel to expand.
• Never smoke when handling fuel, and stay away
from an open flame or where fuel fumes may be
ignited by a spark.
• Store fuel in a clean, safety-approved container
and keep the cap in place.
3. Follow starting instructions.
4. Tighten air bleed screw on top of fuel filter.
Note: Normally, engine should start after above
bleeding procedures are followed. However, if engine
does not start, air may be trapped between injection
pump and injectors; refer to Bleeding Air From
Injectors.
Checking the Operation of the
Interlock Switches
If safety interlock switches are disconnected or
damaged the machine could operate unexpectedly
causing personal injury.
• Do not tamper with the interlock switches.
• Check the operation of the interlock switches
daily and replace any damaged switches before
operating the machine.
• Replace switches every two years regardless of
whether they are operating properly or not.
Caution
1. Be sure that the parking brake is set and all bystanders
are away from the area of operation. Keep hands and
feet away from the cutting units.

the reel switch in the ON position, the dash indicator
light should be glowing and the reel motors turning
