WARNING
Always check equipment for
proper operation before each
use, making sure safety devices
are in place and operating
properly. DO NOT alter or modify
any part of the equipment as this
may cause amalfunction and
result in serious bodily injury.
ATTACHING HYDRAULIC
MOTOR TO PUMPTUBE
1. Tightly attach Tie Rods (Item 38) to
the Mounting Plate (Item 37). (Use
short threaded end of tie rods).
2. Mount hydraulic motor on top of
pumptube outlet body and tightly
connect pumptube coupling nut to
Piston Rod (Item 29).
3. Hand tighten tie rods to the pumptube
with four Nuts (Item 39) supplied with
hydraulic motor.
4. Connect hydraulic supply and return
lines and slowly cycle pump several
times, using only enough pressure to
operate the pump without stalling.
NOTE: Air in the hydraulic motor
may cause slow or erratic shifting
during the first few cycles after
connecting the hydraulic lines.
5. Stop the pump on an “up” stroke and
tighten the four nuts to securely fasten
the hydraulic motor to the pumptube.
WARNING
WARNING
Toreduce therisk ofserious
bodily injury orproperty damage,
