Signal Words:   

This manual uses SIGNAL WORDS to indicate the likelihood of personal injuries, as well as the probable seriousness of 

those injuries, if the product is misused in the ways described. Other signal words call attention to uses of the product likely 
cause property damage. 

The signal words used appear below along with the meaning of each word

 

  

 

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. 

 

 

Identifies a hazardous situation which, if not avoided, COULD result in DEATH or 
SERIOUS INJURY. 

 

 

Indicates a hazardous situation which, if not avoided, COULD result in MINOR or 
MODERATE injury. 

 

                             

Identifies practices likely to result in product/property damage, such as operation that might 
damage the product. 

 

 

 

Safe Use Recommendations: 

Vestil strives to identify foreseeable hazards associated with the use of its products. However, material handling is 

dangerous and no manual can address every conceivable risk. The end-user ultimately is responsible for exercising sound 
judgment at all times.

 

 

 If this product is used or maintained improperly serious personal injuries or death might result.  ALWAYS 

use the product properly. 

 

Failure to read and understand the entire manual before assembling, using or servicing the product 

constitutes misuse

.

 

  Read the manual to refresh your understanding of proper use and maintenance procedures. 

  DO NOT attempt to resolve any issue with the product unless you are both authorized to do so and 

certain

 that it will 

be safe to use afterwards. 

  DO NOT modify the product in any way. Unauthorized modifications might make the lifter unsafe to use and 

automatically void the Limited Warranty (see p. 21). 

  DO NOT exceed the 4,000 lb. capacity, i.e. do not attempt to lift more than 4,000 lb. 

  Inspect the product before each use. Check the lifter for damage, such as: 1) Cracked, broken or deformed load-

bearing members (forks, fork carriage, mast, wheels, and frame); 2) cracked welds; 3) corrosion or severe wear; 4) 
damage to the hydraulic system   including leaks in of any part of the cylinder, hoses, reservoir, etc.). Remove the 
product from service if damage is discovered. Replace each part that is not in normal condition. DO NOT use the 
product until it is fully restored to normal condition. ONLY use manufacturer-approved replacement parts. 

  Cycle the forks all the way up and all the way down. While cycling the forks listen for unusual sounds and watch the 

forks, carriage, cylinder, and carriage rollers for unusual movement. If you discover a malfunction, remove the unit from 
service and notify your supervisor & maintenance personnel about the issue. In the event that part of the hydraulic 
system is damaged, AVOID contact with pressurized hydraulic oil (leaking from a ruptured hose, for instance). High 
pressure oil easily punctures skin which can cause injury like gangrene. 

  DO NOT use the lifter unless all machine guards (e.g. the expanded metal mast guard and formed wheel guards) 

are in place. 

  This product is NOT a personnel lift. DO NOT use it to lift or transport people. 

  DO NOT walk or stand beneath the forks at any time. 

  DO NOT leave the pallet handler unattended while it is loaded. ALWAYS completely lower the forks until the load is 

entirely supported by the ground before leaving the lifter unattended. 

  ONLY transport loads with the forks no higher than necessary to support the load and avoid obstacles. 

  DO NOT continue to push the “UP” button on the hand control if the forks do not respond. Remove the unit from 

service and report the problem to maintenance personnel. 

  Always lift pallets properly. Drive forward until the edge of a pallet contacts the heels of the forks. 

  ONLY use this lifter on even, level ground. 

  NEVER change the setting of the pressure relief valve. 

  ALWAYS carefully watch the pallet handler and the load while lifting and transporting loads.  

  DO NOT use this device UNLESS all labels (see “Labeling Diagram” on. p. 20) are in place, readable, and 

undamaged.
