Inspections & Maintenance
Maintenance Intervals
Before Each Use
Inspect the following:
Frayed wires
Battery surface should be clean and dry. The
battery should be locked down and secured.
Pinched or chaffed hoses
Damage or structural deformation to the
structural members, the cylinder brackets, etc.
Proper functioning of all limit switches, including
those on the perimeter pinch point guard, if
applicable.
Check for load chain damage and for play / slack.
Oil leaks
Monthly
Verify the oil level is between the maximum
and minimum lines.
Worn or damaged hydraulic hoses and
electrical wires
Pivot point wear
Roller looseness and wear
Retaining ring integrity on all rollers and all
pivot points
Clean off dirt and debris as necessary.
Looseness, wear or damage to the front rollers and
drive wheel, bearings, mounting hardware or
surface material.
Proper functioning of any hand or foot operated
mechanisms
Proper water level in battery. Not necessary with a
maintenance-free or gel battery.
Unusual noises or movement during operation
All the information, safety and warning labels are
present, legible and securely attached.
Yearly
The oil should be changed if it darkens,
becomes gritty or turns a milky color which
indicates the presences of water. Replace
with anti-wear hydraulic oil with a viscosity
grade of 150 SUS at 100°F (ISO 32 at 40°C).
E.g. AW 32 or HO 150 hydraulic oil or a non-
synthetic transmission fluid. You may use a
synthetic transmission fluid if you flush the
system with the synthetic fluid before filling the
reservoir.
Check chain and chain linkages for mechanical
damage.
Clean upright channels and mast rollers and grease
slightly.
Check the lift motor’s brushes for carbon built up.
Replace the motor as necessary.
Chain Maintenance
For normal use, load chains should be lubricated every 250 operation hours. In heavy soiling and/or moisture and
spray environments or after high prolonged loading, the chain should be lubricated every 100 operating hours or
sooner if required based on the chain’s extreme environmental conditions. If the chain has been exposed to corrosive
media, it should be cleaned and lubricated immediately.
Chain Lubrication and Conservation
Flyer chains are correctly lubricated and are in a perfect state if:
The chain is free of exterior soiling.
When touched, your finger is wetted with oil. This assures the chain links are sufficiently lubricated.
Lubricant Type
A low viscosity, mineral, machine oil, engine oil or synthetic oil should be used. The oil’s viscosity should be viscous
during all operating, ambient temperatures.
Under normal temperature conditions, lubricating oils with a viscosity of SAE 20 to SAE 40 are appropriate.
