Milton CAT 994F - Manual (Page 8)

Hydraulic System. Completely enclosed
hydraulic system uses separate circuits
for lift and tilt, steering and brake
control. Separate circuits provide
increased cooling and elimination of
cross-contamination, resulting in less
downtime and greater productivity.
Lift and Tilt System. Three dedicated
fixed displacement piston pumps and a
fourth electronically controlled variable
displacement piston pump deliver high
reliability, efficiency and performance
to the lift and tilt system. The variable
displacement pump is only activated
when additional hydraulic speed
is needed.
Pilot Controls. Low-effort, pilot-operated
finger-tip controls provide smooth,
precise control of lift and tilt functions.
Automatic lift kickout and return to
dig detents deliver fast cycle times.
Steering System. The 994F features a
load-sensing steering system with variable
displacement piston pump for smooth,
precise control. The revolutionary
steering system integrates steering and
transmission control functions into a
single controller. Simple side-to-side
movement of the STIC steer lever turns
the machine right or left. Center point
frame articulation allows the machine
to articulate 40° to the left or right,
permitting precise positioning in
tight areas.
Filtration System. Advanced filtration
system consists of additional screens
and filters throughout the lift/tilt, steering
and brake systems to maintain cleanliness,
and prevent downstream contamination.
All are monitored electronically through
VIMS™ system to simplify diagnostic
troubleshooting and reduce downtime.
