JIMMY SERIES HYDRAULIC REBAR BENDERS — MAINTENANCE
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.
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.
Completely change hydraulic oil every 300 hours of operation.
NOTE Change the oil more frequently when pump is used in an extremely dusty environment or when the oil has been overheated.
Use only good quality hydraulic oil.
NOTE 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.
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
