5. Do not wrap load chain around the load or bring the load in
contact with the hoist. Doing this will result in the loss of the
swivel effect of the hook which could mean twisted chain and a
jammed liftwheel. The chain could be damaged at the hook.
6. Stand clear of all loads and avoid moving a load over the
heads of other personnel. Warn personnel of your intention to
move a load in their area.
7. Do not leave the load in the air unattended.
8. Do not lower the hook to a point where the chain becomes
taut between the liftwheel and loose end pin.
9. Do not run the lower hook block into the hoist frame. Frame
and/or chain guide damage may result.
10. The hoist has been designed for manual operation only.
11. Do not use this or any other overhead materials handling
equipment for lifting persons.
12. Do not allow the load to bear against the hook latch. The
latch is to help maintain the hook in position while the chain is
slack before taking up slack chain.
13. Never operate the hoist when flammable materials or vapors
are present. Sharp contact between metal parts can produce
sparks that can cause a fire or explosion.
14. STAY ALERT! Watch what you are doing and use common
sense. Do not use the hoist when you are tired, distracted or
under the influence of drugs, alcohol or medication causing dimin-
ished control.
WARNING
Exceeding the rated capacity of the hoist may cause load to fall.
TO AVOID INJURY:
Do not exceed the hand chain pulls specified in 4 above.
GENERAL INFORMATION
INSPECTION
To maintain continuous and satisfactory operation, a regular in-
spection procedure must be initiated so that worn or damaged
parts can be replaced before they become unsafe. The intervals
of inspection must be determined by the individual application and
are based upon the type of service to which the hoist will be sub-
jected. The inspection of hoists is divided into two general classi-
fications designated as “frequent” and “periodic”.
Frequent Inspections:
These inspections are usually visual examinations by the operator
or other designated personnel. The frequent inspections are to
be performed daily or monthly and shall include the following
items:
a. Braking mechanisms for evidence of slippage — daily.
b. Load Chain for lubricant, wear, damaged links or foreign
material — daily. See below.
c. Hooks for damage, cracks, twists, latch engagement and
latch operation —monthly. See below.
Any deficiencies noted are to be corrected before the hoist is re-
turned to service.
Periodic Inspections:
These are visual inspections by an appointed person who makes
records of apparent external conditions to provide the basis for a
continuing evaluation. For normal service, the periodic inspec-
tions are to be performed yearly and for heavy service, the peri-
odic inspections are to be performed semi-annually.
Due to the construction of the hoist, it will be necessary to par-
tially disassemble the unit to perform the periodic inspections.
The periodic inspections are to include those items listed under
frequent inspections as well as the following:
a. Chain for excessive wear or stretch. See below.
b. Worn, cracked or distorted parts such as hook blocks, hoist
hanger, chain guide, stripper, loose end pin, shafts, gears,
hook collar and bearings.
c. Inspect for wear on the tip of the pawl, teeth of the ratchet
and pockets of the liftwheel and handwheel.
d. Loose or missing bolts, nuts, pins or rivets.
e. Inspect brake components for worn, glazed or contaminated
friction discs and scoring of the handwheel hub, ratchet and
friction hub. Replace friction discs if the thickness is less than
0.044 in. (1.12 mm) on 1/2 & 1 ton units and 0.059 in. (1.50
mm) on 2, 3, 5 and 10 ton units
f. Corroded, stretched or broken pawl spring.
g. Free movement of the pawl on the pawl stud. Also, apply a
thin coat of lubricant to the pawl stud (see page 6) before re
assembling the unit.
h. Hooks — dye penetrant, magnetic particle or other suitable
crack-detecting inspections should be performed at least once
a year, if external conditions indicate there has been unusual
usage.
Any deficiencies noted are to be corrected before the hoist is re-
turned to service. Also, the external conditions may show the
need for more detailed inspection which, in turn, may require the
use of nondestructive-type testing.
Any parts that are deemed unserviceable are to be replaced with
new parts before the unit is returned to service. It is very impor-
tant that the unserviceable parts be destroyed to prevent possible
future use as a repair item and properly disposed of.
HOOK INSPECTION
Hooks damaged from chemicals, deformations or cracks or that
have more than a 10° twist from the plane of the unbent hook or
excessive opening or seat wear must be replaced.
Also, hooks that are opened and those that allow the latch to dis-
engage the tip, must be replaced.
Any hook that is twisted or has excessive throat opening indicates
abuse or over-loading of the unit. Other load-sustaining compo-
nents of the hoist should be inspected for damage.
The chart below should be used to determine when the hook
must be replaced. To measure throat opening, depress the latch
against the hook body as shown below.

WARNING
Power operation may result in structural damage or premature
wear that may cause a part to break and allow the load to fall.
TO AVOID INJURY:
Operate Series 622 Hoists using hand power only.
WARNING
Allowing the load to bear against the hook latch and/or hook tip
can result in loss of load.
TO AVOID INJURY:
Do not allow the load to bear against the hook latch and/or hook
tip. Apply load to hook bowl or saddle only.

are present. Sharp contact between metal parts can produce
