This manual provides user instructions for Vestil trailer stabilizing jacks, including installation, operation, removal, routine maintenance, safety checks, exploded parts views and bills of materials, safety label identification, and warranty information. It applies to models BFSJ-2748, LO-J-BEAM, H-LO-J-BEAM, LO-J, HI-J, SP-TOP, SP-TOP-R, SJ-35, and SJ-35-EF.
The jacks are intended to support the ends of semitrailers on compacted, improved surfaces during loading and unloading. The manual also describes daily and monthly inspections, lubrication of the lifting screw, hydraulic oil requirements for the H-LO-J-BEAM model, and related OSHA guidance.
| Hydraulic oil viscosity grade (H-LO-J-BEAM) | 75 SUS at 100°F (ISO 15 cSt @ 40°C) |
|---|---|
| Hydraulic oil viscosity grade (monthly check) | 70 to 85 SUS at 100°F (ISO 15 at 40°C) |
| Lifting screw lubricant | Standard bearing grease |
They are intended to be used only on compacted, improved surfaces to support the ends of semitrailers.
They should be serviced at least every two months.
A standard bearing grease should be used on the screw.
Use a mineral-based hydraulic oil with a viscosity grade of 75 SUS at 100°F (ISO 15 cSt @ 40°C).
