precautions to reduce the risk of fire, electric shock and personal injury. However, please note that
these instructions and warnings are not substitutes for proper accident prevention measures.
NOTE: The following safety information is not meant to cover all possible conditions and situations that may occur. WEN reserves the right to change this product and specifications at any time without prior notice.
Keep this manual available to all users during the entire life of the tool and review it frequently
to maximize safety for both yourself and others.
Safety is a combination of common sense, staying alert and knowing how your item works.
WARNING: To avoid mistakes and serious injury, read and understand this entire instruction manual.
Learn the tool’s applications, limitations, and possible hazards.
1. Keep your work area clean, uncluttered, and well lit. Cluttered areas invite injuries and accidents. Keep the
ground clear of tripping hazards. Do not work on floor surfaces that are slippery with sawdust or wax.
2. Observe work area conditions. Keep bystanders at a safe distance from the work area. Never allow children or
pets near the tool.
3. To avoid contact and shock hazard, do not use the scaffolding near energized power lines or electrical lines. Do
not contact unprotected, energized electrical power lines or other power sources with the scaffolding or tools. Maintain at least 10 feet from electrical lines. Consult the power company to shut off the power or insulate/relocate lines
if a job requires working closer than 10 feet to electrical lines.
4. Only assemble and use the scaffolding on a flat, level surface capable of supporting the tool with its maximum
capacity load. It is easy to lose control if attempting to pull a load on a sloping or uneven surface.
1. Wear ANSI Z87.1-approved impact safety goggles, a hard hat, heavy-duty work gloves and OSHA-specified safety harness during assembly and use. Wear additional safety gear as required by local, state and federal regulations.
2. Dress for safety. Do not wear loose clothing, neckties, or jewelry (rings, watches, etc.) Always wear non-slip footwear and tie back long hair.
3. Stay alert - watch what you’re doing and use common sense when using the scaffolding. Do not use while you are
tired or under the influence of drugs, alcohol or medication that may affect your ability to properly use the tool. A
moment of inattention while using the scaffold may result in serious personal injury.
1. Follow all current OSHA (Occupational Safety and Health Administration) guidelines for setup, use and maintenance of the scaffolding. Scaffolding safety regulations may change periodically. The operator is responsible for
being familiar with and obeying current OSHA guidelines as well as local, state and federal regulations regarding
the set-up and use of this product.
2. Use the right product for the job. There are certain applications for which this tool was designed. Unauthorized
modification may damage the tool and/or cause personal injuries.
3. Check for damaged or worn out parts before using the scaffolding. Check for alignment of moving parts, jamming, breakage, improper mounting, or any other conditions that may affect the tool’s operation. Any part that is
damaged should be properly repaired or replaced before use. Do not attempt to straighten deformed parts, as this
will weaken their structural integrity. Bent parts should be replaced immediately.
4. Make sure all guards and fasteners are secure after assembly or adjustments. All connections should be tight
before operation.
5. Acids and other corrosive substances may severely affect the integrity of the scaffolding. Use extreme care around
such materials and follow applicable instructions. Do not use acids or other corrosive substances on scaffolding
parts, as they could corrode the metal and decrease its strength.
6. Immediately remove scaffolding from use and discard if exposed to excessive heat (such as fire), which could
cause a loss of structural integrity.
7. Do not permit oil, grease, or other slippery material to accumulate on climbing or gripping surfaces.
8. Do not use the product if the platform surface is damaged or has deteriorated. Only use the included platform or
an identical replacement platform. The platform must not extend beyond the base support.
9. The maximum working load is 1000 pounds evenly distributed for one stage and 750 pounds combined for two
stages. The total combined weight of workers and materials must not exceed the rated working load. Always keep
weight evenly distributed.
10. Be aware of dynamic loading: jumping on or suddenly dropping weight onto the scaffolding may briefly create
an excess load, causing the product to fail.
11. Do not ride on or transport items on scaffolding.
12. Do not allow unstable objects or slippery materials to accumulate on the scaffolding.
13. Do not use for cantilever applications. Use with supports directly underneath the scaffolding.
14. Maintain labels and nameplates on the scaffolding. These carry important safety information. If unreadable or
missing, contact WEN customer service for a replacement.
15. Position the scaffolding on a hard, level surface. Make sure the working/standing surface is completely level and
that the wheels are locked before getting on the scaffolding.
16. Do not climb onto scaffold from a ladder unless both the scaffolding and the ladder are secured from movement
in all directions. Do not use a ladder above the platform to reach greater heights.
17. Use guard rails, mid rails and toe boards (not included) as required by local, state and federal regulations. Using
such safety devices is always recommended.
18. Scaffolds that are covered in ice or snow cannot be used until they are cleaned off thoroughly. Scaffolds must
not be used during storms or in windy weather.
19. Store idle scaffolding out of the reach of children and do not allow persons unfamiliar with the scaffold to climb
on it or use it for any purpose. This item can be dangerous in the hands of untrained users.
20. Have the scaffolding regularly serviced by a qualified person. Use only identical replacement parts and accessories. This will ensure a longer lifespan for the product and will also maximize safety.
These safety instructions can’t possibly warn of every scenario that may arise with this tool,
so always make sure to stay alert and use common sense during operation.

2. Secure the casters in place using a locking pin (4). Then,
snap the pin spring around the end of the locking pin to
keep it in place.
3. Lock the swivel casters in place by pressing down on the
end of the caster plate marked “ON”. Pressing down on
the end marked “OFF” unlocks the caster for movement.
Fig. 1
1. Slide a side rail (1) onto the end frames (2) and secure it
into place using two L-shaped pins (7). The L-shaped pins
must be fully engaged in the holes of the frame.
2. Further secure the frames with a locking pin (4) on each
side of the side rail.
3. Repeat to install the other side rail onto the other side of
the end frames. Both side rails must be positioned at the
SAME HEIGHT on the frames so that the platform will
be level. Check the rails’ level with a bubble level or other
instrument (not included).
Fig. 2
4. Check to make sure all four L-shaped pins (7) and four
locking pins (4) are properly installed.
PINS (Fig. 3)
1. To disengage the L-shaped pin:
Pull out the L-shape pin at each end of the side brace to
disengage it and adjust the platform height.
2. To engage the L-shaped pin:
Release the L-shaped pin and be sure that pin fully engages into holes in the frame.
Fig. 3
WARNING: Make sure the L-shaped pins
are fully locked before operation.
1. Lay the plywood platform (3) over the flange pins that
extend up from the side rails and into the oblong holes
cut in the wood platform. These flange pins must fit
2. Secure the wood platform (3) in place with the platform hold-downs (6).
3. Rotate the platform clips into the engaged position, as
indicated in Fig. 4.
4. If needed, a second scaffold (sold separately) must be
assembled by using the first scaffold as a stable platform.
Refer to the next page for attaching a second scaffold.
Use additional safety devices such as guard rails, mid rails
and toe boards to stabilize the second scaffold.
Fig. 4
WARNING: Before assembling the second stage, the lower stage must be fully assembled even if it is not
being used. The lower stage provides needed structural support for the upper stage. The caster wheels
must be LOCKED to ensure that the lower stage will not move.
Observe all safety rules for boarding, working on, and getting off the first stage when assembling. Assemble the upper stage one piece at a time to help prevent clutter and falling parts. Assemble each major component completely
1. Attach one second stage end frame by inserting the bottom of its legs over the tops of the first stage’s end frames.
Secure into place with locking pins and L-shaped pins.
Repeat the procedure for the other end frame.
2. Attach the side rails one at a time to each side of the
second stage end rails at the desired height. Use the height
adjustment pins, locking pins and L-shaped pins to adjust
the wooden platform to the desired height.
3. Secure the scaffold to a stable structure using ties and/
or braces. They must be secured at the end of the third
horizontal beam on the second scaffolding (the same as
the eighth beam from the ground) as noted in Fig. 6. The
components and the attachment methods used at this
point must be rated to at least four times the capacity of
the scaffolding. If you have any doubts about your ability to
properly do this, employ the help of a qualified technician
4. Lay the wooden platform onto the side rails, making
sure the oval holes fit over the flange pins without having to
be forced.
5. Use the two platform hold-downs along with four screws,
nuts and washers (not included) to secure the wood platform into place.
Fig. 5
WARNING: Do not go any higher than two scaffolds.
Fig. 6
WARNING: To prevent serious injury, make sure all the warnings and instructions have been read and
understood before operating this tool. If you have any questions or concerns, please contact our customer
service at (800) 232-1195, M-F 8-5 CST.
Rated working load (evenly distributed): 1000 pounds for one stage and 750 pounds combined for two
stages. The total combined weight of workers and materials must not exceed the rated working load.
1. Wheel the scaffolding to the area where it is to be used, grasping and pushing the scaffold at points no higher
than five feet from off the floor in order to prevent tipping. The surface where this scaffolding is placed must be
capable of supporting the entire scaffolding plus its maximum load without shifting or settling. Use on concrete or
asphalt only.
2. Lock the swivel casters by pressing down on the lock mechanism attached to each wheel. Pressing down on the
end marked “ON” locks the swivel caster in place. Pressing down on the end marked “OFF” unlocks the caster
for movement.
WARNING: All casters must be LOCKED prior to use to prevent movement and injury. Use a level to
verify that the surface of the wooden platform is completely flat in all directions. Eyeballing the angle of
the scaffold is not accurate enough to maximize safety.
3. Recheck all lock pins for full engagement before accessing the platform. Check the platform to be sure it is
properly seated within the side brace and the platform clips are fully engaged.
4. Do not climb onto scaffold from a ladder unless both the scaffolding and the ladder are secured from movement in all directions. Do not use a ladder above the platform to gain greater heights. Ladders must be clamped
securely in place to the scaffolding to prevent any movement. Any ladder (normal or stairway type) must meet
OSHA requirements for use with scaffolds.
5. If the scaffolding will be accessed directly (such as from an opening in the side of a building), it cannot be more
than 14 inches horizontally and 24 inches vertically from the other surface.
6. Each worker on a scaffold more than 10 feet above a lower level must be protected from falling to that lower
level. Fall protection consists of either personal fall arrest systems or guardrail systems meeting OSHA requirements.
7. For most activities, there must be no more than a 14-inch gap between the wooden platform and the structure
being worked on (unless the work is lathing or plastering - a gap of 18 inches is permitted for this situation).
8. If toe-boards, guardrails or canopies are used to prevent a falling object hazard to passersby, then the areas
below the scaffolding must be barricaded and the danger must be clearly stated to said passersby.
9. All plug-in electric tools used on a scaffold must be protected by GFCI outlets or plugs.
10. When finished using the scaffolding, wipe down the wood platform and all metal supports. Any oily or greasy
substance spilled on the wood platform needs to be cleaned immediately to avoid causing someone to slip and
Procedures not specifically explained in this manual must be performed only by a qualified technician. Only a qualified technician. Only a qualified technician may replace any parts or make any safety equipment additions to this
1. Before each use, inspect the general condition of the scaffold. Check for:
• cracking or detoriating of the reinforced wood platform
• cracked or loosen wheels or wheel locks
• straightness/levelness of the platform and scaffolding
• loose screws
• misalignment of parts
• cracked, bent or broken parts
• any other condition that may affect its safe operation
2. Periodically coat wood decking and rails with transparent (penetrating) wood preservative. Do not paint or use
opaque surface sealants - they may conceal serious problems.
3. Acids and other corrosive substances may severely affect the integrity of the scaffolding. Use extreme care around
such materials and follow applicable instructions. Do not use acids or other corrosive substances on scaffolding
parts, as they could corrode the metal and decrease its strength.
4. After use, clean the external surfaces with a clean cloth and store indoors in a safe, dry area away from children.
5. Use only identical replacement parts and accessories only. This will ensure a longer lifespan for the product and
will also maximize safety. Replacement parts can be purchased by contacting our customer service at (800) 2321195, M-F 8-5 CST
The tool, accessories and packaging should be sorted for recycling instead of disposed of with household waste.
Please take them to your local recycling facility for responsible disposal and to minimize the environmental impact.
