KRAFTWERK 38101 Manuel D'utilisation page 4

The product shall be maintained in accordance with the product instructions. No alterations shall be
made to this product.
1. Before use, a visual inspection of the jack should be made for abnormal conditions such as cracked welds,
damage, bent, worn, loose or missing parts or hydraulic leaks.
2. Inspections shall be performed in accordance with this manual.
3. The product shall be inspected immediately if the jack is believed to have been subject to an abnormal load or
shock. It is recommended that this inspection is made by an authroized customer service representative prior to
use.
Monthly maintenance is recommended. Lubrication is very important for jacks as they support heavy
loads. Any restriction due to dirt, rust etc. can cause either slow movement or cause extremely rapid
jerks, damaging the internal components. The following steps are designed to keep the jack well
lubricated:
1. Lubricate the ram, linkages, saddle and pump mechanism with light oil. Grease wheels bearings and axles.
2. Visually inspect for cracked welds, bent, loose, missing parts or hydraulic oil leaks.
3. If jack is subjected to abnormal load or shock, remove from service and have it examined by a customer service
representative prior to use.
4. Clean all surfaces and maintain all labels and warnings.
5. Check and maintain the ram oil level.
6. Check ram every 3 months for any sign of rust or corrosion. Clean as needed and wipe with an oil cloth.
Always store your jack in the fully lowered position. This will help to protect critical areas from
excessive corrosion.
Do not use brake or transmission fluids or regular motor oil as they can damage the seals. Always
purchase and use products labeled Hydraulic Jack Oil.
The service life of the jack depends on the intensity of use and the orderly compliance with the instructions
contained in the operating instructions (Compliance with these guidelines will optimize the service life of the jack).
When a jack is defective, it must be put aside and identified as prohibited for use.
When a jack is out of service, drain the oil and deposit it with an authorized treatment agent. The other components
of the jack must be disposed of in accordance with local regulations.
1. Turn release valve counterclockwise to allow ram to fully retract. It may be necessay to apply force to the saddle
for lowering.
2. With the jack in the level position, remove the oil fill plug. The oil should be level with the bottom of fill hole. If not,
top off. Do not overfill. Always fill with new, clean hydraulic jack oil type HL or HM with an ISO-grade of kinematic
viscosity of 30 cST at 40°, or an Engler viscosity of 3 at 50°.
3. Replace fill plug.
4. Check jack operation.
5. Purge air from system if required.
