penetrate, cut and/or burn skin.
Do not leave a wrench on the electric outrigger over-ride nut located on top of the electric
outriggers.
TOWING CAUTIONS/WARNING
1. Caution should be taken when towing to avoid high speeds and short turns. Unit may tip over
and this could result in death or serious injury.
1/31/2008 - 11 -
2. Remove all cargo from the scissors lift before towing. Failure to do this could result in
death or serious injury.
3. Do not operate unit in high speed winds, death or serious injury could occur.
4. Tow only with outriggers in transport position
5. Tow only with extension deck retracted and
pinned
6. Tow only with the deck lowered in transport
position
7. All tires must be properly inflated. Find the
recommended cold tire pressures on the tire
sidewall or trailer decal which is located inside
of the bottom control box. Do not over inflate
the tires. Tire pressures go up during driving.
Checking the tire pressure when the tires are
warm will give you an inaccurate pressure
reading.
8. Increase the distance between your vehicle and
the vehicle in front of you to twice the normal
following distance when towing a trailer. Allow
more following distance in adverse weather.
9. Slow down for downgrades and shift your
transmission into a lower gear.
10. Slow down for curves, hazardous road
conditions, freeway exits, and when driving in
adverse weather. Remember that your PLE Lift
may have a center of gravity that is higher than
the vehicle that is pulling it.
11. When passing other vehicles, be sure to leave
enough room for the extra length of the trailer.
You will need to go farther beyond the past
vehicle before you can return to your lane.
12. When turning with a trailer, avoid jerky or
sudden movements.
13. Heavy winds, excessive speed, load shifting or
passing vehicles can cause the trailer to sway
while driving. If this occurs, do not brake, do not speed up, and do not turn the steering
wheel. Turning the steering wheel or applying the brakes can cause the vehicle and trailer
to jackknife. Let up on the gas pedal and keep the steering wheel straight.
14. If the vehicle and/or trailer inadvertently travel off the paved road, hold the steering
wheel firmly and let up on the gas pedal. Do not apply the brakes. Do not turn sharply.
1/31/2008 - 12 -
Slow down to less than 25 mph or 40 km/h. Gradually turn the steering wheel to get back
on the road. Proceed with caution when entering traffic.
15. Always drive slowly when backing a trailer.
16. Keep your hand on the bottom of the steering wheel. Move your hand to the left to turn
the trailer to the left. Move your hand to the right to turn the trailer to the right. Your
PLE Lift has a short wheel base so small moves of the steering wheel have large effects on
the trailer.
17. Be aware of limited sight distance and blind spots when operating.
18. It is recommended that operators wear an approved hard hat when operating the machine.
19. Check the work area for overhead obstructions or other possible hazards.
20. Be aware of crushing hazard when grasping the platform guardrail.
21. Do not operate a machine in the path of any crane or moving overhead machinery unless the
controls of the crane have been locked out and/or precautions have been taken to prevent
any potential collision.
