Hand-operated
hydraulic pump
A hand-operated hydraulic pump kit (MTS part number 038-634-701) is a
required accessory for operating the grips. The kit includes the pump, with shut-
off and release valves, a pressure gage, and hydraulic hoses for connecting the
pump to the grips. The kit also contains an extra supply of hydraulic fluid.
The pump is usually mounted to the base of the load unit (or near it). It includes
two hydraulic hoses; one is 1829 mm (72 in) long; and the other is 2286 mm (90
in.) long.
