OPERATING INSTRUCTIONS
GENERAL
4. The Protector is designed to allow the intermediate gear to
™
slip on an excessive overload. An overload is indicated when
the hoist will not raise the load. Also, some clutching noise may
be heard if the hoist is loaded beyond rated capacity. Should
this occur, immediately release the pup control to stop the
operation of the hoist. At this point, the load should be reduced
to the rated hoist capacity or the hoist should be replaced
with one of the proper capacity. When the excessive load is
removed, normal hoist operation is automatically restored.
CAUTION: The Protector™ is susceptible to overheating
and wear when slipped for extended periods. Under no
circumstance should the clutch be allowed to slip for more than
a few seconds.
Due to the above, a hoist equipped with a Protector
recommended for use in any application where there is a possibility
of adding to an already suspended load to the point of overload.
This includes dumbwaiter (*see below) installations, containers that
are loaded im mid-air, etc.
(*)Refer to limitations on Page i concerning dumbwaiter applications.
Also, if a Lodestar Hoist with a Protector
extremes of ambient temperatures, above 150°F. (106° C.)or below
15°F. (-0° C.), changes in lubricant properties may permit the hoist
to raise larger loads than under normal operating conditions and
present possibility of damage or injury.
5. All hoists are equipped with an adjustable screw limit switch,
which automatically stops the hook at any predetermined point
when either hoisting or lowering.
6. The control station used on two speed hoists is similar to single
speed unit, except that either of two definite speeds may be
selected by the operator in both hoisting and lowering. Each
control when partially depressed provide SLOW speed and
when fully depressed gives FAST speed. Partial release of
control returns hoist to slow speed, while complete release
allows hoist to stop. Rated lifting speeds are shown on hoist
identification plate. SLOW speed is intended as a means
of carefully controlling or "spotting" the load, although the
hoist may be operated solely at this speed if desired. It is not
necessary to operate in the SLOW speed position as the hoist
will pick up a capacity load at FAST speed from a standing
start. In other words, it is not necessary to hesitate at the slow
position when moving control from STOP to FAST position or
vice versa.
7. If material being handled must be immersed in water, pickling
baths, any liquid, dusty or loose solids, use a sling chain of
ample length so that the hook is always above the surface.
Bearings in the hook block are shielded only against ordinary
atmospheric conditions.
HOIST
1. Before picking up a load, check to see that the hoist is directly
overhead.
2. WHEN APPLYING A LOAD, IT SHOULD BE DIRECTLY
UNDER HOIST OR TROLLEY. AVOID OFF CENTER
LOADING OF ANY KIND.
3. Take up a slack load chain carefully and start load easily to
avoid shock and jerking of hoist load chain. If there is any
evidence of overloading, immediately lower the load and
remove the excess load.
4. DO NOT allow the load to swing or twist while hoisting.
5. DO NOT allow the load to bear against the hook latch.

HOIST WITH LOW HEADROOM TROLLEY

This unit should be moved by pushing on the suspended load or
by pulling the empty hook. However, the unit can also be moved by
pulling on the control station since an internal steel cable extends
the length of the control cord and is anchored to the hoist and to the
control station.

HOIST WITH MOTOR DRIVEN TROLLEY

This unit should be moved by operating the controls marked
u(Forward) and t(Reverse) in control station. Unless altered by the
erector, depressing u(Forward) control will move the hoist toward
motor housing end. Anticipate the stopping point and allow trolley
to coast to a smooth stop. Reversing or "plugging" to stop trolley
causes overheating of motor and swaying of load.

SAFETY PROCEDURES

13
(ENGLISH)
1. For safety precautions and a list of DO'S and DO NOT'S for
safe operation of hoists, refer to page ii.
2. When preparing to lift a load, be sure that the attachments
to the hook are firmly seated in hook saddle. Avoid off center
loading of any kind, especially loading on the point of hook.
3. When lifting, raise the load only enough to clear the floor or
support and check to be sure that the attachments to the hook
and load are firmly seated. Continue to lift only after you are
assured the load is free of all obstructions.
4. DO NOT load hoist beyond the rated capacity shown on hoist
identification plate or on the hoist motor housing cover or hoist
back frame cover. Overload can cause immediate failure of
some load-carrying part or create a defect causing subsequent
failure at less than rated capacity. When in doubt, use the next
larger capacity of CM Lodestar Hoist.
5. DO NOT use this or any other overhead materials handling
equipment for lifting persons.
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 suspended in the air unattended.
8. Permit only qualified personnel to operate unit.
9. DO NOT wrap the load chain around the load and hook onto
itself as a choker chain. Doing this will result in:
a. The loss of the swivel effect of the hook which could mean
a twisted chain and a jammed lift wheel.
b. The upper limit switch is by-passed and the load could hit
the hoist
c. The chain could be damaged at the hook.
10. On two and three part reeved hoists, check for twists in the
load chain. A twist can occur if the lower hook block has been
capsized between the strands of chain. Reverse the capsize to
remove twist.
11. 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.
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.
12. Take up a slack load chain carefully and start load easily to
avoid shock and jerking of hoist load chain. If there is any
evidence of overloading, immediately lower the load and
remove the excess load.
13. Do not allow the load to swing or twist while hoisting.
14. Never operate the hoist when flammable materials or vapors
are present. Electrical devices produce arcs or sparks that can
cause a fire or explosion.
15. 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
diminished control.
