Figure 2-5. Hoist Performance Charts.
Note: Hoist Speeds are shown in feet per minute (f.p.m.)
Maximum lowering speed with rated load is very high.
Adjust with care. Heads of adjusting screws should not
extend beyond outer surface of housing.
CAUTION
c. When the screwdriver slots on ends of adjusting screws are
horizontal (hoist in normal suspended position), the hoist speeds
will be at either minimum speed or maximum speed. Rotating
the screws 1800 in either direction will give a full adjustment
between minimum and maximum speed limits. Note: Screws
have arrow stamped on end to assist operator with adjustment.

SECTION III -OPERATION
3-1. GENERAL. Operation of BUDGIT Air Hoists is controlled
by either pull cords or a pendant throttle control, depending
upon the model. Pull Cord Control models have pull type
control cords (Figure 3-1) suspended from a rocker type lever
at bottom of hoist that actuates the throttle control valve.
Pendant Throttle Control models have a convenient lever type
control valve handle (Figure 3-2) suspended from the control
cylinders on sides of control head housing.
Do not lift more than rated load except for test
purposes. Overloading hoist can result in chain
breakage, hook deformation and other failures which
can cause serious injury and damage. A test at greater
than rated load should be a properly supervised official
test only, not an operator test. If any load sustaining
parts have been altered, replaced or repaired, hoist
should be load tested at 125% of rated load by a
designated, qualified person, with a written report
recording test load, as recommended in ANSI B30.16
Safety Standards.
WARNING
3-2. PREOPERATIONAL CHECKS. Check the following before
operating hoist with load:
a. Inspect chain anchor connections at side of hoist frame and
at upper hook or lug mounting bracket on 3/4 and 1 ton double
reeved models. Anchor screw or pin should be secure and not
bent or broken. Chain should be solidly anchored.
b. Check hoist brake for proper adjustment and operation. Refer
to Section V, paragraph 5-2, d.
c. Check hooks. They should not be bent or distorted and should
not be opened beyond the correct opening sizes given in Figure
5-3. Hook latches should not be bent or damaged and springs
not broken.
d. Check chain to make sure it is not twisted or kinked. Be sure
lower block (3/4 and 1 ton, double reeved models) has not
been capsized.

100 psi (while hoist is operating), it is recommended that a
pressure regulator valve be provided in the air supply line to
maintain proper pressure. However, there is a wide range of
pressures within which the hoists will operate. Refer to
“Performance Charts.” See Figure 2-5.
2-4. HOISTING AND LOWERING SPEED ADJUSTMENTS.
a. Hoist speed is adjusted at the factory to give maximum
lifting speed and is set at average between‘ minimum and
maximum lowering speed.
b. To adjust the hoisting or lowering speed, turn appropriate
regulator_ screw (Figure 2-4) in either direction a little at a
time while operating hoist under load.
Never operate hoist with defective chain anchor pins,
brake or hooks.
WARNING
e. Lubricate chain per paragraph 4-4.
