4. Instrukcja obsługi
4.1 Leveling Your RV/Trailer
- Assess Level: Use a spirit level or an RV leveling app to determine which side or end of your vehicle needs to be raised.
- Position First Block: Place one Valterra Stacker block directly in front of the tire(s) that need to be raised. Ensure the block's ramp feature faces the tire.
- Drive On: Slowly drive the vehicle forward until the tire is partially onto the first block.
- Add More Blocks (if needed): If more height is required, place additional blocks behind the first one, interlocking them securely. The easy-grip handle on each block acts as a ramp for the next block.
- Continue Driving: Slowly drive the vehicle further onto the stacked blocks until the desired level is achieved.
- Sprawdź poziom: Re-check the vehicle's level. Adjust as necessary by adding or removing blocks.
- Bezpieczny pojazd: Once level, engage the parking brake and place wheel chocks on the opposite side of the leveled wheels to prevent any movement.
4.2 Using as Jack Stands
Valterra Stackers can be used as temporary jack stands to support the vehicle's frame or axle after it has been lifted by a jack. Stack the required number of blocks to the desired height, ensuring they are securely interlocked. Place the stacked blocks directly under a sturdy part of the vehicle's frame or axle, ensuring the weight is evenly distributed. Always use in conjunction with a primary jack and never rely solely on these blocks for vehicle support during maintenance or tire changes.
4.3 Using as Tongue Wheel Support
For trailers with a tongue jack, Valterra Stackers can be placed under the tongue wheel or foot to provide additional height or stability, especially on soft ground. Stack blocks as needed to prevent the tongue jack from sinking or to achieve the desired height for hitching/unhitching.

6.1 Instability Issues
If the stacked blocks feel unstable, immediately cease operation. Ensure the ground is firm and level. Re-stack the blocks, making sure each block is fully interlocked and centered. Verify that the tire or jack point is fully supported and centered on the top block. Always use wheel chocks on non-leveled wheels.
6.2 Difficulty Stacking
If blocks are difficult to interlock, check for any debris or foreign objects in the interlocking grooves. Ensure blocks are oriented correctly. If blocks are warped or damaged, they should be replaced.
