General Safety Information
DISCONNECT POWER AND RELEASE ALL SYSTEM
PRESSURE BEFORE SERVICING THIS EQUIPMENT.
1. Follow all local electrical and safety codes, as well as the
National Electrical Code (NEC) and the Occupational
Safety and Health Act (OSHA).
2. Never exceed the maximum operating speed or pres-
sure.
3. When using AC motors, ground the motor properly by
wiring with a grounded, metal-clad raceway system,
using a separate ground wire connected to bare metal
of the motor frame, or other suitable means.
4. Guard all moving parts.
5. Drain all liquids from the system before servicing.
6. Check hoses and connections for security before each
use.
7. Periodically check the pump/fluid motor and system
components.
8. Provide a means of pressure relief for pumps whose
discharge line can be shut off or obstructed.
9. Wear safety glasses at all times when working with
pumps/fluid motors.
10. Keep work area clean, uncluttered and properly light-
ed; replace all unused tools and equipment.
11. Keep visitors at a safe distance from the work area.
12. Make the workshop child-proof with padlocks, master
switches, and by removing start keys.
13. Do not operate an engine in an enclosed area.
14. Do not spill gasoline on hot engine surfaces.
15. Store gasoline only in an approved container.
16. Keep dirty and oily cleaning rags in a tightly closed
metal container.
17. Check engine oil level before operating the engine.
18. Familiarize yourself with the controls and emergency
shutdown procedures.
19. Never operate the equipment when you are fatigued.
20. All system components pressure ratings should be
greater than maximum system pressure.
21. Guard all moving parts.
22. Replace all guards when servicing is complete.
Assembly
Models 4F649 through 4F659 are packaged fully assem-
bled and require no further assembly.
Installation
MOUNTING PUMP/FLUID MOTOR ASSEMBLY
TO FLEXIBLE COUPLING DRIVE SYSTEMS
1. Assemble the flexible coupling half to the pump/fluid
motor shaft.
Do not force coupling half onto drive shaft; it must
be a slip fit for adjustment and to avoid internal dam-
age.
2. Tighten the setscrew and insert rubber spider in cou-
pling half.
3. Assemble the other coupling half loosely to the
engine/motor shaft.
4. Bolt the pump/fluid motor loosely to the SAE type
four bolt mounting pump adapter as furnished by the
equipment manufacturer.
5. Align the shafts to make sure they are on center with
each other.
6. Tighten the mounting bolts.
7. Mate the coupling halves together, allowing 1/16”
gap between halves.
8. Check the alignment again.
IMPORTANT: THE GAP IN THE COUPLING HALVES
IS TO PREVENT END LOADING OF THE PUMP/
FLUID MOTOR DRIVE.
9. Tighten the setscrew in the mating coupling half.
10. Remove plastic shipping plugs from the inlet and
outlet ports.
11. Squirt clean oil into pump for pre-lubrication and
start-up.
12. Turn shaft coupling slowly to ensure proper shaft
alignment and coupling installation.
13. Connect inlet and outlet lines with an SAE straight
thread fitting and tighten.
Flush all lines and fittings of contamination.
THREADS ARE SAE,
NOT
NPTF. USING INCORRECT
FITTINGS COULD DAMAGE THE HYDRAULIC
COMPONENT OR CAUSE PERSONAL INJURY.
NOTE: Do not use teflon tape; the O-ring provides the
seal and teflon tape is not required.
14. When using the assembly as a pump keep inlet hose
short and of adequate size to avoid pump cavitation.
NOTE: Cavitation is recognized by excessive noise and
foaming of hydraulic fluid.
Never run assembly without hydraulic oil.
15. At initial start-up, turn the drive shaft several times by
hand to prime.
16. Bleed all air from the system to prevent erratic opera-
tion.
17. After several cycles, check the reservoir oil level and
refill as necessary.
