8.6 DRILLING GUIDELINES

Double check the position of the ramp frame and ramp fixations prior to drilling holes. Use the dimensions in section 7.4 on
page 14 and the instructions in 8.4 on page 20 and 8.4.5 on page 24 as guidelines.

Mark the drill positions on the vehicle floor.

Temporarily place the ramp further inwards or take it out again to be able to work comfortably.

Check if the drill pattern on the vehicle floor can be reproduced at the underside of the vehicle. Verify if all bolts and nuts can
be mounted properly, together with the large washers or flanges to spread the forces of the bolts over a wider area. Reposition
the ramp frame and ramp fixations if required.

Verify the fixation points and prepare solutions in the event that drilling interferes with chassis beams, fuel tank or other vehicle
components, spare wheel carrier, etc.

Refer to the FITTING AND BODY BUILDING INSTRUCTIONS of the vehicle manufacturer, as some have strict procedures
how to execute the chassis drills.

Drill the vehicle floor on the markings you made earlier with a ø11mm drill.

Properly deburr all freshly made chassis perforations. Apply adequate anti-corrosive protection (zinc-spray, Dinitrol, etc.) and
allow to dry.
NOTICE

All drilling works most be executed in accordance with the FITTING AND BODY BUILDING INSTRUCTIONS of the vehicle
manufacturer.

ALWAYS use reinforcement tubes whenever instructed to do so or whenever they are included in the bolt kit of the lift.

All metal works (drilling, cutting, grinding) to the chassis, subframe, rear cross member and vehicle body require adequate
anti-corrosion protection.
