OPERATION
VARIOUS TYPES OF WORK
When rst learning to operate the Track Horse,
position the throttle to the “SLOW” position. More
experienced operators may use higher throttle
settings.
FORWARD TRAVEL
• The throttle can be positioned anywhere between
slow and fast for traveling forward depending on the
weight of the load being carried. Heavy loads will
require higher throttle settings and low range in or-
der for the engine to provide enough power to move
the load.
• A switch mounted on the control provides two-speed
(FAST & SLOW) operation.
REVERSE TRAVEL
•
DO NOT attempt to travel in reverse with the throttle
positioned above “SLOW”. This may result in loss of
control and result in injury or death to the operator.
Always position the throttle to a slow position for re-
verse travel to permit increased control and safety.
ENGINE SHUTDOWN
Place both control levers in the OFF position. Push the
throttle control completely in. Allow the engine to idle for
approximately one minute, turn the switch to OFF, and
then pull the stop knob to shutdown the unit. Make sure
the start switch is in the off position.
HYDRAULIC TOOL CIRCUIT CONTROLS
The MHP3 TracHorse provides two circuits, each with
an oil ow of 5 gpm/19 lpm up to 2000 psi/140 bar. Or
the two circuits may be combined into one circuit provid-
ing 10 gpm/38 lpm up to 2000 psi/140 bar.
The MHP3 TracHorse contains a hydraulic pump with
two sections. Each pump section will provide 5 gpm/19
lpm at the maximum, governed engine throttle. The out-
put (5 gpm/19 lpm) of each pump section is directed to
the panel control valve assembly. It is the position of
the hydraulic circuit combiner knob on the panel control
valve assembly which keeps the output of each pump
section separated or combined.
When the hydraulic circuit combiner knob is pulled out,
the two circuits are combined into one 10 gpm/38 lpm
circuit. One hydraulic tool may be connected to one cir-
cuit. The other circuit must not have a tool connected to
it or have the hoses connected. The circuit is activated
by pushing both control levers up.
When the hydraulic circuit combiner knob is pushed in,
the two circuits are not combined and each circuit pro-
vides 5 gpm/19 lpm. One hydraulic tool may be connect-
ed to each circuit. Each circuit is activated by pushing
the circuit lever up.
Oil ow is regulated by pulling the throttle control to the
full throttle position. This setting will produce 10 gpm/38
lpm up to 2000 psi/140 bar.
