STUMP GRINDER OPERATING INSTRUCTIONS
READ SAFETY INSTRUCTIONS BEFORE OPERATING! Both the SAFETY INSTRUCTIONS and
OPERATING INSTRUCTIONS are in this manual.
Be sure that the engine oil and fuel, and the machine hydraulic fluid are all at proper levels before starting
the engine.
STUDY AND UNDERSTAND CONTROLS BEFORE BEGINNING OPERATION.
CONTROLS
1. KEYED IGNITION SWITCH: Used to start and stop the engine with an electric starter.
VANGUARD: The key switch is located on the engine adjacent to the choke and can be seen while
standing behind the machine.
Refer to the ENGINE START UP PROCEDURE.
2. THROTTLE: Controls engine speed. Operate at full throttle when cutting (all the way forward).
3. TRACK CONTROL: Controls the travel direction and speed.
•Track controls are designed to be operated with two hands.
•Pushing the control handles forward from neutral position causes the machine to move forward.
•Pulling the control handles back from neutral position causes the machine to move backward.
•Moving the track control handles farther from the neutral position increases the speed.
•Steer the machine by moving one track control handle farther than the other handle. This causes the
track on one side to rotate at a different speed than the opposite track. Pivot turns can be made by
moving one control forward and the other control back.
