Basic Safety Instructions
Before starting the machine, read and understand these operating instructions.
5.2
Main Components and Operating Elements
Below is a description of the main components of the SG30 Stump Grinder and how
they operate.
5.3 Engine and Drive
The Honda GX390 is a four stroke engine that runs on
standard unleaded fuel.
The engine is air cooled and therefore it is important
that the grille covering the recoil rope is kept clear from
debris.
The engine air filter cleans the air sucked in by the
engine. A clogged air filter will reduce performance.
The engine is fitted with a fuel on/off lever and a choke lever. Read the engine
operating instructions to understand the operation of these levers.
5.4
Operating Lever
The engine of the SG30 Stump Grinder is controlled
by the Operator Presence Control (OPC) lever (fig. 3).
This lever turns the engine ON or OFF.
Squeezing the Operator Presence Control lever allows
the engine to be started.
Letting go of the Operator Presence Control lever
turns the engine off.
5.5
Throttle Lever
The throttle lever controls the engagement and speed of the rotor disc and teeth.
If the throttle lever is in the SLOW position the engine revolutions of the crank shaft
is too low for the centrifugal clutch to engage and transfer power to the rotor shaft
and cutting disc.
Positioning the throttle lever in the FAST position will engage the centrifugal clutch
and the rotor shaft and cutting disc will rotate.
WARNING: MOVING THE THROTTLE FROM SLOW TO FAST MUST ALWAYS
BE CARRIED OUT IN A CONTROLLED MANNER WITH THE OPERATOR UNDER
COMPLETE CONTROL OF THE MACHINE.
