LUBRICATION
NOTE: TO ASSURE LONG LIFE AND TOP PERFORMANCE,
BE SURE TO LUBRICATE THE VARIOUS PARTS OF
THE XL AIR HOIST USING THE LUBRICANTS
SPECIFIED BELOW. IF DESIRED, THESE LUBRCANTS
MAY BE PURCHASED FROM THE FACTORY.
HOIST LUBRICATION
Gears.
Check the oil level in gear housing at least once a
month, maintaining it at the bottom of oil level hole in
the main housing (652-110).
Drain the housing every 2-3 years and refill with one gal-
lon (3.86 liters) of gear oil Hulbest EP ISO VG 68 thru 460
(H-2 Classification).
CAUTION: THE PROTECTOR IS DESIGNED TO OPERATE
IN THE ABOVE MENTIONED OIL. DO NOT
USE ANY OTHER TYPE OF LUBRICANT OR
THE PROTECTOR WILL NOT OPERATE PROP
ERLY AND PARTS COULD BE DAMAGED.
Chain Guides, Liftwheel & Sheave Wheels.
When the hoist is disassembled for inspection and/or
repair, the chain guides, sheave wheels (on multi-reeved
units) and liftwheel must be lubricated with Lubriplate Bar
and Chain Oil 10-R (Fiske Bros. Refining Co.) prior to
reassembly. Apply sufficient lubricant to obtain natural
runoff and full coverage.
Load Chain.
Keep chain lubricated with a small amount
of lubricant. This will greatly increase the life of load
chain. Do not allow the chain to run dry.
Keep it clean and lubricate at regular intervals with
Lubriplate Bar and Chain Oil 10-R (Fiske Bros. Refining
Co.) or equal lubricant. Normally, weekly lubrication and
cleaning is satisfactory, but under hot and dirty conditions,
it may be necessary to clean the chain at least once a day
and lubricate it several times between cleanings. When
lubricating the chain, apply sufficient lubricant to obtain
natural runoff and full coverage.
Bearings.
All bearings except the lower hook thrust bear-
ings are pre-lubricated or are in an oil bath and need no
lubrication. The lower hook thrust bearing should be lubri-
cated at least once a month with heavy duty machine oil.

WARNING
The lubricants used in and recommended for the XL Air Hoist
may contain hazardous materials that mandate specific han-
dling and disposal procedures.
TO AVOID CONTACT AND CONTAMINATION:
Handle and dispose of lubricants only as directed in applicable
material safety data sheets and in accordance with applicable
local, state and federal regulations.
!
WARNING
Used motor oils contain known carcinogenic materials.
TO AVOID HEALTH PROBLEMS:
Never use used motor oils as a chain lubricant. Only
use Lubriplate Bar and Chain Oil 10-R or equal as a
lubricant for the load chain.
Service Air Line Lubricator.
The air line filter and
lubricator is the only source of lubrication for control
valves and air motor. Fill lubricator with a good grade
air tool oil or 10W machine oil Feed one drop of oil for
every 50 to 75 cubic feet of air going through the air
motor.
Miscellaneous.
If the unit is disassembled, splines
inside the coupling (652-103) should be coated with an
EP type grease (such as Evans Products Co. Anti-Scoring
Extreme Pressure Lub. No. 3) before reassembly.
TROLLEY LUBRICATION
Trackwheel bearings are pre-lubricated and require no
lubrication.
Geared Trolley.
Once a month lubricate trackwheel
gears with Texaco Novatex No. 2 or an equivalent heavy
cup grease or graphite grease.
Every six months lubricate handwheel shaft bearings in
3-in-1 machine oil.
Motor Driven Trolley.
Once a month lubricate track-
wheel gears with Texaco Novatex No. 2 or an equivalent
heavy cup grease or graphite grease.
For 2-7 1/2 ton trolleys, the right angle worm gear reducer oil
should be changed after the first 100 hours of operation, then
after every 2500 hours of normal service. When replacing oil
due to repairs or service, use Mobil SHC-626 or equal, for
each oil change.
ADJUSTMENTS
HOIST BRAKE
The correct air gap between spacer tube and field plate when
brake is not activated, is 0.025 inch (.63 mm) and need not be
adjusted until the gap reaches 0.045 inch (1.14 mm).
To adjust the brake, proceed as follows:
1.
Turn off air supply and bleed stored air by depressing
pendant paddles.
2.
Remove brake end cover.
3.
Before adjusting the gap, back off the brake nuts
and examine friction linings and friction surfaces for
wear, scoring or warpage (min.thk. .188). Any of
these symptoms indicate the need for replacement
of parts.
4.
Turn brake nuts clockwise gaging the air gap on
all three posts..
5.
Replace cover, turn on air supply and check operation.
