7.4 Attaching and detaching a bicycle (VAR PR-72000 clamping arm)
The by,schulz e-Bikelifter BM-65 VA and the BM-65-S VA come with the PR-72000 clamping arm by VAR.
This clamping arm can be swiveled 360°, and is suitable for clamping tubes with diameters from Ø 22 mm
up to Ø 80 mm. The two replaceable rubber clamps with their double cable gap provide a secure grip, and
protect components and paint from scratches. The VAR PR-72000 clamp is approved for loads up to 60 kg.

The clamping device consists of two separate parts. The base mounting
plate, which is fixed to the e-Bikelifter, and the interchangeable clamping
arm.
Base mounting plate:
A: Pivot lock lever
B: Allen head screw M5 (Hex 4 mm)
Clamping arm:
C: Rubber clamping jaws
D: Crank for clamping strength fine adjustment with eccentric base
(OPEN)
E: Crank for clamping strength fine adjustment with eccentric base
(CLOSED)
To quickly adjust the clamp to different tube-diameters, the crank has an
eccentric base, which can enter two different conditions. In the „OPEN“
fig. [D] condition, the crank’s knob points towards the clamp, and the
clamping jaws are open. In the „CLOSED“ fig. [E] position it points away
from the clamp, and the clamping jaws are tighter. By simply turning this
crank, the width of the clamp jaw opening can be quickly opened or
closed. Fine adjustment of the opening width, and the clamping force, is
made with the crank. Turning the crank clockwise increases the clamping
force, turning it counterclockwise reduces it.
Beware, that the eccenter has to be in the „CLOSED“ position fig. [E] while
working on a bicycle!
Attaching the bicycle :
1:
Place bicycle on the floor in front of the e-Bikelifter.
2:
Adjust the sledge to the necessary height, by using the foot switches.
3:
Use pivot lock lever fig. [A] of the base mounting plate to rotate the clamping arm and to adjust it to the
clamping situation.
4:
Use the crank fig. [E] to adjust the opening of the clamping arm approximately to the diameter of the
tube to be clamped.
5:
Turn over crank fig. [E] to the „OPEN“ position fig. [D], to widely open the clamping jaws.
6:
Place the clamping area of the bicycle between the clamps fig. [C].
7:
Flip the eccentric fig. [D] back to the "CLOSED" position fig. [E] and use the crank to fine-tune the clamp-
ing force. Turn clockwise to tighten the clamping.
Detaching the bike:
1:
Lower the sledge by using the foot switch, until the wheels of the bicycle touch the ground.
2:
First reduce the clamping force by turning the crank approx. four turns counterclockwise. Now open the
clamping completely by folding the closed eccentric fig. [E] into the open state fig. [D].
3:
Then remove the bicycle.
Note when attaching or detaching the bicycle:
l
Ensure that the pivot lock lever fig. [A] of the base mounting plate is closed tight, and the
clamping arm can’t rotate.
l
To prevent damage, only attach clamps to parts of the bicycle that are strong enough.
l
A slip clutch is preventing damage in case the bike hits the ground while lowering.
l
No obstacles must be on the base plate, when operating the e-Bikelifter.
l
Mind your limbs while working with the e-Bikelifter.
