SAFETY PRECAUTIONS
• Do not work under the vehicle when the engine is
running. Do not work on any part of the hydraulic
system while the pump is running. Do not go near
any leaks when pump is running.
• High pressure oil easily punctures skin causing
serious injury, gangrene or death. If injured, seek
emergency medical help. Immediate surgery may
be required to remove oil. Never use ngers or
skin to check for leaks. Always lower load or relieve
hydraulic pressure before loosening any ttings.
• A serious or fatal injury can occur if you:
◦Lack proper training
◦Fail to follow proper operating procedures
◦Fail to use proper tools and safety equipment
◦Assemble components improperly
◦Use incompatible/incorrect components
◦Use worn or damaged components
INITIAL HYDRAULIC SYSTEM
STARTUP
1. Have appropriate hydraulic oil ready to use.
Non-foaming hydraulic oil is required. MD-Kinney
recommends Shell Tellus “T” series ISO 32 or
equivalent.
2. Fill the Torex with the above listed hydraulic oil.
3. After Torex is lled, check for hydraulic system
leaks.
4. Slowly engage the P.T.O. and pump. Stop when
level drops in the Torex tank to just below the oil
sight glass.
5. Disengage the P.T.O.
6. Re-ll Torex and repeat step 4 until oil level in tank
does not drop while the P.T.O. is engaged.
MAINTENANCE
1. Change hydraulic oil every 6 months*
2. Change hydraulic oil lter every 6 months*
3. Check oil level on a weekly basis, with hydraulic
system o.
4. Visually check all ttings, hoses, and mounting
equipment on a weekly basis, with hydraulic
system o.
5. Follow manufacturer recommendations for all PTO
and pump installation and maintenance.
*Oil analysis program recommended to determine
ideal oil and lter change frequency.

NORMAL OPERATION
Visual Checks Prior to System Start:
1. Check that oil level is within oil sight glass level.
2. Remove any obstructions from radiator and fan.
Starting Hydraulic System:
1. Ensure brake is applied.
2. Ensure control valves are in neutral position.
3. Engage PTO per manufacturer’s instructions.
4. Oil level may drop if air is trapped in system. Stop
system and top o tank if necessary.
5. Operate the valving slowly.
6. To stop the system, follow the above steps in
reverse.
SUCTION LINE INSTALLATION
GUIDELINES
Special attention should be given to applications
utilizing unusually heavy or large diameter piping.
When excessive loading or insucient support of the
suction piping exists, reservoir fatigue fractures, loss of
oil, and decreased hose life are likely to occur.
For all applications, conrm that the weight and
length of pipe work and ttings is not excessive
enough to create vibration or exing issues. If weight
is found to be excessive, shorten the piping to reduce
vibration and/or add support brackets to compensate
for the added weight. Additional support brackets
should be attached to a common point with the Torex
so that exing of the truck frame and vibration does
not induce additional stress on the Torex.
MOUNTING THE TOREX
HYDRAULIC COOLER
Behind the cab is the preferred mounting method.
Frame rail mount may also be acceptable, but should
be the secondary choice.
1. Only use the mounting bracket, capscrews,
washers and nuts supplied to mount the Torex.
2. Be sure to allow 4”of space between radiator and
any solid obstruction that will eect air ow into
radiator.
3. Radiator must be shielded from rocks and road
debris.
HYDRAULIC HOSES AND FITTINGS
1. Extra care should be taken to ensure that no tape
or pipe dope is able to contaminate the hydraulic
system.
2. All hoses are customer supplied. Fit all hoses as
per separate system drawings provided by MD-
Kinney.
3. All high pressure hoses must have a working
pressure rating equal to or higher than the
hydraulic system relief valve setting.
4. The suction hose must be suitable for 28”Hg
vacuum service.
5. Hoses must have proper support near the
Torex to reduce loading from hose and uid
weight. Unsupported hoses pull on the welded
connection ttings of the reservoir and may result
in reservoir stress fractures and shortened hose
life.
6. All hoses should use the largest bend radius
possible to reduce pressure drop and loading.
Always follow the hose manufacturer’s
recommendations for hose duty and bend radius.
If an excessively tight bend is required, consider
using a section of rigid pipe such as a street 90
with increased pipe diameter.
