SIGNAL WORDS
SIGNAL WORDS appear in this manual to draw the reader’s attention to important safety-related
messages. The following are signal words used in this manual and their definitions.
SAFETY INSTRUCTIONS
Vestil strives to identify foreseeable hazards associated with the use of its products, but no manual can
address every conceivable risk. Minimize the likelihood of injury by observing the hazards identified below
and by inspecting and maintaining the product as instructed in INSPECTIONS & MAINTENANCE on p. 10-11.
WARNING
Risks of serious personal injuries or death.
•Read and understand the entire manual before assembling, using or servicing the crane.Read the
manual to refresh your understanding of proper use and maintenance procedures whenever necessary.
•DO NOT use the crane unless the required ballast is installed in the counterbalance box. Ballast
specifications appear on your SPECIFICATIONS document. See page 4, 5, or 7.
•DO NOT attempt to lift items that weigh more than the capacity of your crane. The capacity of the
crane decreases as boom length increases. Capacities of each model for all 3 boom lengths are provided
on your SPECIFICATIONS document as well as on label 1157. See LABELING DIAGRAM on p. 11.
•ONLY use the crane on even, level, compacted surfaces capable of supporting the combined weight of
the crane and a full capacity load. DO NOT attempt to move the crane up or down sloped surfaces.
•DO NOT stand or sit on either the crane or the load. Avoid contact with the casters.
•Stand clear of the load while raising and lowering it.
•DO NOT perform maintenance on this crane UNLESS it is unloaded and both caster brakes are applied. If
the crane requires repair, ONLY install manufacturer-approved replacement parts.
•DO NOT attempt to raise a load unless the load hook is centered above it.
•ALWAYS observe the boom while raising or lowering a load. Watch for binding or jerky movement. Listen
for unusual noises. Tag the unit "Out of Service" and do not use it if you observe anything abnormal.
•DO NOT use the crane unless it is in satisfactory condition. Inspect the unit before each use and as
instructed in the Inspections section on p. 9-10 to determine whether it is in SATISFACTORY CONDITION.
•Always watch the load carefully while raising and lowering the boom.
•Before leaving the crane unattended, unload it and lower the boom to relieve hydraulic pressure.
•DO NOT alter the pressure relief valve setting!
•DO NOT use the crane UNLESS every label is present and readable. See LABELING DIAGRAM on p. 11.
•DO NOT modify this crane in any way. Modifications automatically void the LIMITED WARRANTY and
might make the crane unsafe to use.
•Always make sure that the shackle pin is secure before applying a load to the load hook. Tighten the
shackle pin before each use. See USING THE CRANE and corresponding diagrams on p. 8.
•Failing to maintain, or repair, the crane could make the crane unsafe to use and result in serious personal
injuries or death. Only qualified personnel should perform maintenance and repairs.
NOTICE
Proper use and maintenance are essential for this product to function properly.
•Always use this product in accordance with the instructions in this manual and consistently with any
training relevant to devices used in conjunction with this product (e.g. rigging).
•Periodically lubricate pivot points.
•Keep the product clean & dry.
•Only use approved replacement parts. Contact TECHNICAL SERVICE to order replacement parts.
DANGER
Identifies a hazardous situation which, if not avoided, WILL result in DEATH or
SERIOUS INJURY. Use of this signal word is limited to the most extreme situations.
WARNING
Identifies a hazardous situation which, if not avoided, COULD result in DEATH or
SERIOUS INJURY.
CAUTION
Indicates a hazardous situation which, if not avoided, COULD result in MINOR or
MODERATE injury.

TABLE OF CONTENTS Rev. 4/22/2022 CBFC, MANUAL
TABLE OF CONTENTS Copyright 2022 Vestil Manufacturing Co. Page 8of 12
RAISING AND LOWERING THE BOOM
This floor crane utilizes a modular power unit (MPU) to control the up and down movement of the
boom and load hook. To activate the power unit, turn the power selector switch ON, pull out the
emergency stop button (E-stop) and press the appropriate control button (UP or DOWN) on either the
MPU or the handheld controller.
Pressing and holding the UP button causes oil to fill the cylinder. As oil fills the cylinder, it extends. The
moving end of the cylinder attaches to the bottom of the outer boom. As the cylinder extends, the end
of the boom and the load hook are elevated. Press the UP button until the load hook is adequately
elevated for your task.
Lower the boom by pressing the DOWN button on either the MPU or handheld controller. Release the
button when the boom is lowered to the desired point.
USING THE CRANE
1) Carefully push the floor crane to the load. Apply both caster brakes by pressing down on the brake
levers. See diagram below.
2) Attach appropriate rigging to the load. Rigging will attach to the load hook at the end of the boom.
3) If necessary, adjust the position of the boom.
a. Raise the boom by pressing the UP button on either the MPU of the
handheld controller.
b. Lower the boom by pressing the DOWN button on either the MPU or
the handheld controller.
4) Attach the rigging to the load hook. The floor
crane must be on a sound, level and dry
surface. Before raising the boom, be sure
that the load hook is centered above the
load. If the hook is not centered above the
load, the load might swing when the boom
lifts it off of the ground.
NOTE: Rigging and all other load-engaging
equipment must be added to the weight of
the load to determine the net weight of the
load applied to the crane. The net weight
must be less than or equal to the rated load
of the crane. Rated load for each model of
crane decreases when the boom is
extended. Refer to your SPECIFICATIONS
document (see page 4, 5, or 7); see also
label 1153 in LABELING DIAGRAM on p. 11.
5) Slowly raise the load until it is suspended a
few inches above the ground. Do not
elevate the load any more than necessary.
a. The load should not swing as it rises.
b. The crane should not tip or rock when the
load is suspended.
c. If the crane is unstable when the load is
suspended, do not use the crane to transport
the load. Return it to the ground and use
another means to move it.
6) Transport the load by carefully pushing the
crane to the destination. Turn slowly. Stop
slowly to minimize load swing. Do not leave
the crane with a suspended load. Always
lower the boom until the load is entirely
supported by the ground or other surface
before leaving the crane.

RECORD OF SATISFACTORY CONDITION
Before putting the crane into service, describe the appearance and functions of the crane in writing.
Include observations about each part of the crane. Photograph the unit from multiple angles. Include
close range photographs of pivot points and pins, the hydraulic system (cylinder, modular power unit,
hose(s), and oil tank), hooks, shackles and shackle pins, casters, and caster brakes. Use the crane to lift
a test weight. Raise and lower the boom. Include notes about sounds heard while the power unit
operates and the cylinder extends and retracts (boom elevates and lowers, respectively). Thoroughly
photograph the unit and all labels applied to it. Collect all writings and photographs in a file. This file is a
record of the crane in satisfactory condition. Create a corresponding RECORD for the modular power
unit as instructed in the MPU-DC GEN2 owner manual.
INSPECTIONS & MAINTENANCE
WARNING
Lower the boom and unload the crane BEFORE beginning maintenance/repairs. Apply both caster
brakes. Only qualified, authorized personnel trained to maintain hydraulic components should attempt
troubleshooting and repair of this equipment.
Inspections and repairs should only be performed by qualified persons. Compare the results of each
inspection to the RECORD OF SATISFACTORY CONDITION. Do not use the crane unless all parts are in
satisfactory condition. Replace parts that are not in satisfactory condition before returning the unit to
service. Never make temporary repairs of damaged or missing parts. Only use manufacturer-approved
replacement parts to restore the unit to satisfactory condition. DON’T GUESS! If you have any questions
about the condition of your lifter, contact the TECHNICAL SERVICE department. The phone number is
provided on the cover page of this manual. Apply all relevant inspections as instructed in the MPU-DC
GEN2 owner manual as well.
(A) Before each use, inspect the following items:
AIR PURGING PROCEDURE
The cylinder is designed to automatically purge air. If
sponginess is observed when the cylinder is extended, unload the
crane and cycle the cylinder a few times, i.e. fully extend the
cylinder and then completely retract it.
The cylinder includes an integral velocity fuse. The purpose of
the fuse is to prevent the cylinder from retracting too rapidly in the
event of a sudden loss of hydraulic pressure. A sudden loss of
pressure could result if, for example, a hose is punctured. If the
cylinder will not retract and the hydraulic system is intact (no
leaks, punctures, etc.) the velocity fuse is probably closed.
Contact TECHNICAL SERVICE for assistance.
BOOM LENGTH ADJUSTMENT
To adjust the length of the boom, raise the boom until it is level. Remove the hitch pin and flat
washer and then pull out the clevis pin. The inner boom is now unfastened from the outer boom. Align
the appropriate hole
s in the inner and outer booms to achieve the necessary boom configuration
and then re-pin them.

TABLE OF CONTENTS Copyright 2022 Vestil Manufacturing Co. Page 10 of 12
1) Hydraulic system: Check all fittings, couplers, and the oil tank for oil leaks and other damage.
Also check the hose for cuts, kinks, leaks, or other damage.
2) Frame elements, cylinder brackets (connection points of cylinder to the frame), & booms (inner
and outer): Examine each item for damage, deformation, and rust and corrosion.
3) Cylinder and pump (part of the MPU): Raise and lower the boom. Listen for unusual noise;
watch the cylinder to confirm that it extends and retracts smoothly (does not bind). Check
cylinder seals for leaks.
4) Load hook and shackle: Thoroughly examine the load hook, shackle, and shackle pin for
significant wear, warps, bends or cracks. Make sure that the shackle pin is tight. Confirm that
the safety latch (of the hook) operates correctly. Also inspect the shackle bracket. The bracket
should be square and rigid and lack cracks and significant bends. The pin hole (for the shackle
pin) should not be elongated.
(B) Inspect the following at least ONCE PER MONTH:
1) Oil level: Lower the boom completely. Oil should be within ¾in. of the top of the reservoir with
the boom in the fully lowered position. See YEARLY INSPECTION below for the hydraulic fluid
specifications.]
2) Hoses:Check for cuts, kinks, and other damage. Confirm that the fittings at the ends of the
hose are firmly connected to the pump and to the cylinder.
3) Hardware: Check the integrity of all nuts, bolts, and pins. Replace any item that is damaged.
4) Casters: Move the crane and determine whether any caster is loose, significantly worn, or
damaged. Remove any material stuck to the surface of the casters.
5) Crane overall: Listen for unusual noises and watch for abnormal movement while elevating and
lowering the boom. The frame should be square and rigid. Examine welds. Make sure all welds
are intact and are free of rust and corrosion.
6) Labels: Check all labels applied to the product. The crane must be labeled as shown in the
LABELING DIAGRAM on p. 11.
(C) Yearly inspection
In addition to BEFORE EACH USE and MONTHLY inspections, check the hydraulic fluid at least once
per year. Change the oil if it darkens, becomes gritty, or turns a milky color (indicating the presence of
water). Replace the hydraulic fluid with anti-wear hydraulic oil of viscosity grade 150 SUS at 100°F, (ISO
32 at 40°C), for example, AW 32 or HO 150 hydraulic oil, or a non-synthetic transmission fluid. You may
use a synthetic transmission fluid if you flush the system with the synthetic fluid before filling the reservoir.

LIMITED WARRANTY
Vestil Manufacturing Corporation (“Vestil”) warrants this product to be free of defects in material and
workmanship during the warranty period. Our warranty obligation is to provide a replacement for a
defective, original part covered by the warranty after we receive a proper request from the Warrantee

from an authorized distributor AND Vestil has been fully paid.
Definition of “original part”?
An original part is a part used to make the product as shipped to the Warrantee.
What is a “proper request”?
A request for warranty service is proper if Vestil receives: 1) a photocopy of the Customer Invoice that
displays the shipping date; AND 2) a written request for warranty service including your name and phone
