PRE-ERECTION JOB SITE INSPECTION & PREPARATION
The following guidelines are not all inclusive; rather they are examples of job site conditions to be aware of.
A survey of all obstructions, impediments or encumbrances that would pose a danger during the entrance onto the job site,
during the course of working on the job site and during the exiting of the job site should be taken prior to arrival of the equipment at the
job site.
This shall include, but is not limited to, aerial, ground and any buildings surveys. It shall include such potential hazards as:
Uneven ground, untamed earth fills, ditches/trenches, holes or depressions in the ground.
Electrical power, distribution lines. Guy wires
Protrusions from out of the ground or overheard from buildings or poles.
Debris, unguarded openings, hazardous conditions created by other trades or unauthorized people on the job site.
Weather conditions and forecasts and other possible unsafe conditions.
All potential hazards should be corrected or flagged and barricaded.
iThe common types of accidents scaffolding and mobile work platforms are most likely to be involved in are tip over,
collapse, and electrocution.
iTip over would most likely be caused by one or a combination of the following: wind, uneven ground conditions,
overloading and/or failure to keep uprights vertically plumb or failure to properly erect equipment.
iCollapse would most likely be caused by overloading or failure to properly erect equipment.
iElectrocution would most likely be caused by failure to lower platform(s) and/or remove the upright extensions to maintain
safe clearances of electrical power distribution lines. KNOW THE HEIGHT AND VOLTAGE OF ALL POWER LINES ON AND
ADJACENT TO THE JOBSITE. KNOW THE HEIGHT OF ALL EQUIPMENT AND MATERIALS BEING USED AT THE JOBSITE.

--GENERAL INSPECTION & MAINTENANCE—
Daily visual inspection shall be conducted of the structural components and other critical components, such as pin, bolts and locking
devises (including pawls). Check for metal/weld fatigue on all parts including slide mechanism on platforms. Check for bent or worn
parts or components that need maintenance, repair or replacement. When parts or components need replacement, they shall be
identical or equivalent to original parts or components.
Environmental conditions such as acidic rain, salt water air or extremely wet conditions can have an impact on various equipment
parts and must be taken into account when determining if inspections should be made more frequently than the recommended
minimums. Amount of use and amount of towing should also be taken under considerations to determine if inspections should be
made more frequently than the recommended minimums.
The following are minimum frequency recommendations regarding the inspection and maintenance of the unit:
KEY: D-Daily W-Weekly M-Monthly
D 1. Check to be sure Instruction Manual is in Instruction Manual storage holder
D 2. ALL decals are in place and legible
D 3. Check brake handles, they should move easily. Oil or grease pivot.
D 4. Lock brakes. If wheels turn easily, re-adjust brake adjusting bolt on brake band until wheel is securely locked. If
wheels still turn, brake band linings are probably damaged-replace.
D 5. Check tire pressure & wear. Maintain maximum recommended tire pressure. Replace worn out tires. Tires
should be matched sets on each axle. Check lug nuts for tightness.
D 6. Front & Rear tongue bolts tight.
D 7. Is Rear steering tongue working properly. CHECK BEFORE TOWING ON STREETS & ROADS.
D 8. Check Extension Ladder safety catch; it should move freely.
D 9. Ladders should not have bent or broken rungs.
D 10. Check winch cables. If frayed or badly pinched, replace. Make sure Hair pin clips are in place.
D 11. All guardrails are straight, in place, and secured with ¼” safety pins.
D 12. Entry latches are in working order.
D 13. All x-brace are straight. Check for excessive wear or metal cracks at connections and/or brackets.
W 14. Inspect cable sheaves & clevis pins for wear. Lubricate with heavy oil or grease
W 15. Check lift arm ropes for wear and/or deteriorations, replace as needed.
W 16. If uprights or extensions have been bent or severely twisted-replace.
W 17. Grease inside lip of uprights to prevent lift arms from binding or dragging.
W 18. Grease adjusting arm threads, two zirks per arm. Oil ball joints located on each end of arms.
W 19. Grease platform slide brackets and inspect for cracks and/or metal fatigue.
W 20. All toe boards are in place and in good conditions.
W 21. Inspect decking for holes, soft spots or any other deterioration.
M 22. Grease front & rear axles, three zirks per axle.
M 23. Check the wheel alignment for proper tow.
M 24. Grease wheel bearings and check for play. Should be repacked at a minimum-annually.
M 25. Inspect reach pipe bolts & square washers for wear.
M 26. Reach pipe is straight, not bent. CHECK BEFORE TOWING ON STREETS & ROADS.
M 27. Check spherical tierod ends for wear.
M 28. Inspect the lift arm pawls & springs for wear & tension.

TROUBLE SHOOTING
If you have trouble raising and/or lowering the platform(s), check the following items:
1. Grease the inside lips of the front & rear uprights and upright extensions.
2. Grease the slide mechanism of the platform.
3. Be sure that the uprights are in line. If they are too out of line, the binding of the platform at the lift arm attachment pints
will transfer to the uprights and make it very hard to raise and/or lower the platform.
4. Is one or both of the uprights bent? Replace if needed.
5. Are the cables on the sheaves at the top of the uprights? Is the hair pin cotter in place to prevent cable from slipping off of
sheave?
6. Are the sheaves out of round or worn out? Replace entire sheave or brass busing insert. Oil brass sheave bushings.
7. Is the cable threaded through the space between the upright and the welded on backbone (u-shaped)? It should not be.
8. If you have a model 195 (goes to 25’6” deck height), do not thread the cable through the eye located just above the winch.
9. Is the winch free turning or is the cable wound over itself?
10. Check the welds of the slide mechanism, where it is welded to the platform. Are any of the welds broken? This would cause
the platform & slide to bind and work against each other.
TOWING
Poor towing can be a combination of several factors, including speed and road conditions. Check each of the following before
continuing to the “Guide to Proper Steering Alignment”.
1. Keep each axle free and non-binding.
2. Keep Front & Rear tongue bolts tight (snug).
3. A bent reach pipe or tie rod(s) can cause towing problems. Replace.
4. Use matched pairs of tires on each axle. Inspect tires for out-of-round or being severely out of balance.
5. Inspect rims for being out-of-bound or bent. Make sure the lug nuts have the rims securely on hubs.
6. Check for excess play of the wheel bearings.
7. Check for excess play of the tie rod ends and hairpin connections.
GUIDE TO PROPER STEERING ALIGNMENT
1. Keep all side play out of tongue by tightening 5/8” bolts at Point C.
2. FRONT TIRES: Align Front hairpin and tongue with center reach pipe and set tow in by sight or string as shown in drawing.
Viewed from the front, the point of projection on the Rear tire should be 1-1/2” from the inside face. (See Drawing Below).
The differential in measurement from the Front Point A to Rear Point B of the Front tires should be ½” to ¾”. With the
distance at Point A being the smaller of the two.
REAR TIRES: The Rear steering tongue must be in the latched position. Viewed from the rear, the Rear tires should align
with the front. The differential in the measurement of the front of the Rear tires to the back of the Rear tires should be 0”
or no toe in.
