ROUTINE MAINTENANCE & SAFETY CHECKS
• Care should be taken to identify all potential hazards and comply with applicable safety procedures before beginning work.
• Fully lower the carrier to the floor before beginning any inspection or work on the unit.
• Only qualified individuals trained to understand mechanical devices and their associated electrical and hydraulic circuits should
attempt troubleshooting and repair of this equipment.
(A) Before Each Use Inspect Any and All Safety Devices
1.) Frayed wires.
2.) Oil leaks.
3.) Pinched or chafed hoses.
4.) Damage to the foot pump treadle.
5.) Damaged or loose carrier door or chain binder.
6.) Damage or structural deformation to the structural members, the cylinder brackets, etc.
7.) Unusual noise or binding, or evidence thereof.
8.) Floor lock makes solid contact with floor surface.
9.) Proper functioning of any limits.
(B) Monthly Inspections
1.) The oil level. Oil should be 1" to 1-1/2" below the reservoir's fill hole with the carrier fully raised.
2.) Worn or damaged hydraulic hoses and electrical wires.
3.) Wear or damage to the foot pump treadle or its hardware, the pump piston, or the release lever.
4.) Damage or excessive wear to the carrier parts, gears and chains.
5.) Pivot point wear at the hinge pins and cylinder ends.
6.) All pins and clevis retaining rings and/or fasteners are intact.
7.) Looseness, wear, or damage to the casters' bearings, mounting hardware, or surface material.
8.) Excess wear to the floor lock friction pad.
9.) Proper water level in the battery. (DC units only.)
10.) Unusual noises.
11.) Information and warning labels being in place and in good condition.
12.) The need to clean off dirt and debris.
(C) Yearly Inspection
The oil should be changed if the oil darkens, becomes gritty, or turns a milky color (indicating the presence of
water). Replace with an anti-wear hydraulic oil with a viscosity grade of 150 SUS at 100°F, (ISO 32 @ 40°C). Ex: AW-32 or
HO 150 hydraulic fluid, or Dexron transmission fluid.
