Manual Override Procedure for MH 4 System
Note: Not all systems have this manual override option
Pump #s 2390, 2532, 2542, 2015, 2017
Your hydraulic motor may be equipped with a manual override output shaft. You
must use a drill with a 7/16" or ¼” Allen driver.
The drill must be capable of producing a minimum of 2000 r.p.m. for the pump to
develop appropriate pressure output.
Your pump assembly may have a hand pump in place of the motor with manual
override shaft. If this is the case, you may pump the hand pump in lieu of using the
2000 r.p.m. drill and the 7/16” or ¼”) socket driver.

Care must be taken to ensure neither the drill nor the socket contact any
wires or hydraulic hoses while in use.

The hand pump may be found on pump #s 1551, 2015, 2017
