DAMAGED EQUIPMENT POLICY
Safety Statement
At Workforce, we are dedicated to the safety of all users of our products. Therefore, all
Workforce lifts are designed, manufactured and tested to comply with current applicable
Federal OSHA and ANSI codes and regulations.
Damage Policy
There may be occasions when a Workforce lift is involved in an incident that results in
structural damage to the lift. This can seriously compromise the ability of the lift to perform in a safe manner. Therefore, whenever a Workforce lift is damaged structurally or
when there is the possibility of structural damage (this damage may be internal and is not
always visible to the naked eye), Workforce requires that the lift be returned to our facility at 125 Taylor Parkway, Archbold, Ohio, for reconditioning. If you have any questions
concerning what constitutes structural damage, please call the Workforce Service Department at 419.445.9675.
Damage Repair Notice
There may be occasions when a Workforce lift is involved in an incident resulting in nonstructural damage. When this occurs and repairs are made by the owner or area distributor, please notify Workforce of these non-maintenance repairs and request a repair form
to be filled out and returned to Workforce.

Introduction

GENERAL DESCRIPTION
The model XLT-1071 Cougar Lift is designed and manufactured for use as a warehouse
stocking and order picking machine. Its unique guard rail design permits the operator to
ride on the platform with the load, while transferring it from group level to its overhead
storage location. The maximum platform load is limited to 500 lbs.
Platform elevation is accomplished by means of a 1-1/2 inch displacement type hydraulic
cylinder. The lower telescoping section is pushed vertically upward by the cylinder while
the upper sections are raised by a mechanical motion advantage accomplished through
two sets of chains and sheaves. The platform is raised three inches for each one inch of
cylinder extension. Platform elevation and descent is controlled by pushbuttons on the
upper control box located on the platform.
Safety of operation is assured by proper inspection and maintenance procedures as set
forth in this manual. The possibility of platform free-fall is eliminated by proper maintenance and replacement of the chains, sheaves and sheave pins, a properly installed flow
restrictor valve, and a clean mast. The non-adjustable restrictor valve controls and fixes
the rate of platform descent whether empty or fully loaded to approximately 0.6 feet per
second. A hydraulic hose failure will result in the same rate of descent, eliminating freefall, when the restrictor valve is installed properly.
Emergency lowering of the platform is accomplished by means of a manual control valve
located on the hydraulic manifold block assembly, next to the pump/motor unit.
The Cougar Lift features a displacement type of cylinder that will not rust or corrode during storage since the cylinder rod is immersed in oil. It is important that the cylinder rod
be kept clean and undamaged for the protection of the cylinder head packing.
The floor lock safety switch prevents the unit from raising until the two floor pads have
been properly engaged and helps to make the Cougar Lift a safe, dependable machine.
Carefully read all the safety instructions contained in Section 1 of this manual before operating the Cougar Lift.

LIFT CHAINS AND SLIDE BLOCKS
WARNING
Do not operate a unit on which any chain assembly is damaged or in need of replacement. Operating a unit with a damaged chain can cause severe injury or
death to personnel and damage to equipment.
Inspect all lift chains daily. Inspect for signs of wear, split leaves, loose pins, clevis damage, and elongation. Replace any chain which is damaged in any way. Chain assemblies
may be ordered from your dealer or direct from the factory. Do not operate a unit on
which any chain assembly is damaged and in need of replacement.
Chain Elongation Inspection
One pitch of chain should measure 5/8 in. (1,5875 cm). Measure 20 pitches of chain. The
ideal measurement for 20 pitches of chain should be 12.5 in. (31,75 cm). Replace the
chain if 20 pitches measure over 12.75 in. (32,385 cm). Refer to Figure 3-4.

Lift Chain Adjustment
1.
Raise the platform to the maximum extended height and then lower it while
someone checks to see that all sheaves are turning and checks for chain damage
or wear.
2.
After the platform is completely lowered, remove the plexiglass cover from the
base.
3.
Chains should be tight to the touch with no loose play. Check all four lift chains
for snugness. If a chain is loose, tighten the lock nut below the clevis retainer.
Refer to Figure 3-5. Adjust any loose chain until it just becomes snug. Do not
overtighten any chain so that the platform is raised from its resting position.
4.
Make sure the lock nuts are turned onto the threaded clevis ends with at least 1/8
in. of the clevis end extending through the nut. Replace any lock nut which does
not stay in position during use. Replace the plexiglass cover.

Slide Block Adjustment
Annually check for wear on the slide blocks and replace or retighten as necessary. If the
lift exhibits excessive mast sway, it is probable that the slide blocks need adjustment. The
slide blocks should be adjusted so that there is no air gap between the slide block and the
mast the slide block is moving against. There are 12 slide blocks, 6 upper and 6 lower.
The adjustment procedure is the same for all slide blocks. Three upper slide blocks are
shown in Figure 3-6.
1.
Loosen, do not remove, the slotted hex head screw securing the slide block to be
adjusted.
2.
Using an allen wrench, turn the set screws in (clockwise). This will push the
block in against the next mast. Do not overtighten. Tighten the slotted hex head
screw to secure the slide block in position.
3.
Check all slide blocks and make adjustments as necessary.
4.
After all adjustments are made, fully extend the lift. If the platform can be lowered without stopping then the blocks are properly adjusted.

provided upon each rental or lease delivery. Copy(ies) of operating and maintenance
manual(s) shall be provided upon each sale delivery. The operating manual(s) shall be
stored in the location required by 4.18. These manual(s) are considered an integral part
of the aerial platform and are vital to communicate necessary safety information to users
and operators.
5.3 Predelivery Preparation. Aerial platforms shall be inspected, serviced, and
adjusted to manufacturer's requirements prior to each delivery by sale, lease, or rental.
5.4 Maintenance Safety Precautions. Before adjustments and repairs are started on an

the "off" position and all operating features secured from inadvertent motion by brakes,
blocks, or other means. (2) Powerplant stopped and starting means rendered inoperative
(3) Platform lowered to the full down position, if possible, or otherwise secured by
blocking or cribbing to prevent dropping (4) Hydraulic oil pressure relieved from all
hydraulic circuits before loosening or removing hydraulic components (5) Safety props
or latches installed where applicable as described by the manufacturer.
5.5 Replacement Parts. When parts or components are replaced, they shall be identical
or equivalent to original aerial platform parts or components
5.6 Training. Whenever a dealer directs or authorizes an individual to operate an aerial
platform, the dealer shall ensure that the individual has been trained under the direction of
a qualified person in accordance with the manufacturer's operating and maintenance
manual and requirements listed in Section 8 before operating the aerial platform.
5.6.1 Training on Delivery. Manufacturer's operating instruction and required
training on the proper use and operation of the aerial platform shall be provided upon
each delivery, by sale, lease, or rental.
5.7 Operation. When a dealer operates an aerial platform in sales demonstrations or for
other beneficial use, the dealer shall assume the responsibilities of users as specified in
Section 7 and the operating personnel shall assume the responsibilities of operators as
specified in Section 8 of this standard.
5.8 Assistance to Owners and Users. If a dealer is unable to answer an owner's or
user's question relating to rated capacity, intended use, maintenance, repair, inspection,
or operation of the aerial platform, the dealer shall obtain the proper information from the
manufacturer and provide that information to the owner or user.
6-1
