2. Mounting
 All Deli YBZ series DC power units utilize
the same bolt pattern-3/8-16 x ½” deep,
the holes are 3.25 inches apart
 Torque mounting bolts to 25 ft-lbs-Steel
reservoirs larger than 6 liters must be
mounted using the support tab/tabs
located at the end of the reservoir
opposite the DC motor.
 Some poly reservoirs may require a
support brackets depending the
application. Please consult Deli
Hydraulics for reconditions.
3. Hydraulic Hoses & Connections
 Never Crack Hydraulic Fitting When
Pressurizes Cracking hydraulic fittings or
hoses under pressure can result in severe
injury.
 If Hydraulic Injection Occurs Seek
Medical Attention Immediately Hydraulic
injection may initially resemble a bite or
sting
 Never route Hydraulic Hoses around or
across sharp edges that may cause
chafing and damage to rubber insulation
 Never route Hydraulic Hoses near
moving parts that may pinch or chafe
rubber insulation
 Check Hydraulic Hoses Regularly
Check for cracks or wear on hydraulic
hoses. If you can see steel braiding your
hoses need to be replaced.
 Always Use Hoses and Fittings
Intended for Use on Hydraulic
Equipment Consult fitting specifications
and relief valve setting when selecting
Hoses and Fittings.
 All ports are #6 SAE O-ring boss.
 Lubricate all O-rings before installation
 For an additional manifold mounted to
unit consult equipment mfg. for
specifications
 For adjustable o-ring fittings back nut off
a few turns, insuring the o-ring id is not
on fittings threads
If thread sealant is required use liquid thread
sealant. If Teflon tape must be used; 1.5 to 2
wraps is plenty. Insure no tape is over the end of
the fitting
4. Electrical
 Reference the Battery Cable Selection
Chart to ensure the proper gage battery
cable has been selected for power unit
location
 Never route electrical around or across
sharp edges that may cause chafing and
damage to cable/wire insulation
 Never route electrical near moving
parts that may chafe or pinch cable/wire

Electrical Connections
 When tightening studded electrical
connections the nut only needs to be
tight enough to collapse the spring lock
washer.
 Ensure all spade connections are
secure.
 Check electrical connect regularly for
corrosion and tightness.

Negative Cable from Battery/Ground
 Single terminal DC motors are internally
grounded - Connect Negative cable from
battery to the side of the DC motor.
 Two terminal DC motors have an
isolated ground – The Battery cable must
be connected to the Ground stud on the
DC motor. (the stud with the cable
connected to the start solenoid is the
positive stud. The negative wire will have
a ground wire connected to the base of
the start solenoid)
5. Filling reservoir
 Notice two lined on dipstick of Breather
cap
 The top line indicates maximum fluid
level
 The bottom line indicated the
minimum fluid level
 Fill reservoir to the top line on dipstick of
breather during initial start up.
 Fill reservoir to fill line on dipstick after air
has been cycled out of the system
