pressures up to 3675 psi (25,339 kPa).
Never disconnect any hydraulic line or
fitting without first dropping pressure
to zero. Failure to comply may result in
serious injury or death to personnel.
Fuel and oil are slippery and can cause
S
falls. To avoid injury, wipe up spilled
fuel or oil with rags.
Compressed air used for cleaning purposes
S
