manual for reference when servicing the lifter or trouble-shooting a deficiency.

NSPECTION

CHEDULE

Perform inspections routinely, according to the following frequency schedule:

Every-Lift Inspection

• Examine the vacuum pads and load surface for contamination or debris (see V

ACUUM

AINTENANCE

to follow).

• Examine the vacuum pads, controls and indicators for visual damage (see V

ACUUM

AINTENANCE

to follow).

• Test the battery for adequate charge (see B

ATTERY

EST

to follow).

If a battery’s charge appears to be inadequate, charge and retest the battery (see B

ATTERY

ECHARGE

to follow). If any other deficiency is detected during the inspection, correct it before

using the lifter and perform the Frequent Inspection to follow.

Frequent Inspection

(

following every 20-40 hours’ use; or whenever lifter is out of service for 1 month or more)

• Examine the lifter’s structure for visual damage.
• Examine the vacuum system (including vacuum pads, fittings and hoses) for visual damage.
• Examine the air filters for conditions requiring service (see A

ILTER

AINTENANCE

to follow).

• Perform the V

ACUUM

EST

to follow.

• Check for unusual vibrations or noises while operating the lifter.
• If the lifter is equipped with a Remote Control System, perform the R

EMOTE

ONTROL

YSTEM

EST

to follow.

If any deficiency is detected during the inspection, correct it before using the lifter and perform

the Periodic Inspection to follow.

Periodic Inspection

(

following every 250-500 hours’ use; or whenever lifter is out of service for 1 year or more)

• Examine the entire lifter for external evidence of looseness, excessive wear, deformation,

cracks, excessive corrosion, dents to structural or functional components, cuts, or any
deficiency which might constitute a hazard.

• Inspect all parts of the electrical system for damage, wear or contamination that could

constitute a hazard, in compliance with all local codes and regulatory standards that are
relevant for the geographical region.
