PREVENTIVE MAINTENANCE
Preventive maintenance should be performed on a daily or
weekly basis depending on the amount and working use. A
higher than normal operating pressure could indicate a need
for immediate maintenance.
A clean well lubricated rebar bender will operate faster and
smoother and will allow for more accurate readings from
pump pressure gauges.
PUMP MAINTENANCE (Cleaning and Lubrication)
1. Remove the side plates on the rebar bender to expose
moving parts. Clean all moving parts with a clean rag
and solvent.
2. Check the cylinder on all models for leaks.
3. Lubricate all moving parts with
high pressure grease
.
4. For rebar bender models with cables (Models JB11090
and JB9180), lubricate the five grease fittings daily or
after approximately 50 rebar bend operations. Check
hydraulic cables daily for fraying.
4. For rebar models JB135 and JB7135, visually check for
dents or cracks in the side plates. Replace plates
immediately if damaged. Clean and lubricate both rollers
to insure smooth rotation.
5. Check hydraulic oil every 40 hours of operation. Add
hydraulic oil if necessary. Oil can be added by removing
the vent cap. Use a funnel.
ADDING HYDRAULIC OIL
1. Make sure electric motor is OFF.
2. Depressurize system by placing pump control lever in
the
neutral
position. Disconnect hydraulic hose from
port A of system.
3. Remove
vent cap
on top plate of reservoir. Visually
inspect to see if oil level is low. Oil level should be about
2 inches (50 mm) from top of reservoir plate.
4. Using a funnel, add oil to about 2 inches (50 mm) from
top of reservoir plate.

STORAGE
When the rebar bender and electric hydraulic pump are not
used, please store in a clean dry location out of the reach of
children and away from unauthorized personnel.
Be sure that all dust caps are attached to their respective
hoses and the hand-held remote control cable and pump
power cord are neatly wrapped.
CHANGING HYDRAULIC OIL
1. Change hydraulic oil
once a year
.
2. Remove drain plug, tilt the pump, then pour used fluid
into a sealable container.
3. Dispose the hydraulic fluid in accordance with local
regulations.
4. Install drain cap.
5. Remove vent cap and fill with recommended type
hydraulic oil.
NOTE
Completely change hydraulic oil
every
300 hours
of operation.
Change the oil more frequently when
pump is used in an extremely dusty
environment or when the oil has
been overheated.
NOTE
Use only good quality hydraulic oil.
Multiquip recommends Mobil DTE
15M or equivalent. NEVER use
brake fluid, transmission fluid,
turbine oil, motor oil alcohol glycerin
etc. Use of other than the
recommended hydraulic oil will void warranty and damage the
pump and hydraulic hose used in the rebar bending application.
