Floor Level Cam Adjustment:

The floor level cam(s) are located on the lower drive

arm shaft, on the rear side of the frame tube (under

the cover). Adjust per application.

• Stepwell Application (Figure Q)

1. Position platform at floor level.

2. Loosen the two cam screws.

3. Adjust the cam for proper switch activation.

4. Tighten the two cam screws.

• Dropped Floor Application (Figure R)

• Up-Stop Adjustment (inner cam and switch):

switch):

Activated when the platform switches from the

up/down positions to the stow/deploy positions.

1. Position platform at lowered floor level.

2. Loosen screws A and C.

3. Adjust the outer cam until the floor level

switch activates.

4. Tighten screws A and C.

Deploy Limit Switch Adjustment (Figure S)

This switch adjusts the angle of the platform when

positioned at floor level. The platform should be

level with the van floor. The switch is located on the

vertical arm where the switch arm pivots.

1. Position platform at floor level.

2. Loosen the screw that secures the cam to the

vertical arm.

3. Level platform using a level (or as needed).

4. Adjust cam so the deploy limit switch activates.

5. Tighten screw.

6. Verify position and check level.

Raising the platform more than 3” off of the

ground is prevented unless the outer barrier is

raised.

Verified:

Vehicle movement is prevented unless the

passenger only. Do not use

the electrical override to oper-

ate the lift when a passenger is

on the platform. Lift functions

operate at higher rate of speed

when using the electrical over-

ride. When using the electrical

override, the operator must stop

pressing the applicable override

switch when the lift reaches the

desired position (limit switches

will not function).

Note: Following electrical

override procedures, press the

two override rocker switches to

NORMAL. Close access cover

and press the main control

switch to STOW. Function lift

proper operation.

The Electrical Override feature

is provided as a diagnostic

procedure to reset the system

and as an alternative method

of operating the lift without a

Proper maintenance is necessary to ensure

safe, troublefree operation. Inspecting the lift for

any wear, damage or other abnormal conditions

should be a part of your daily routine. Simple

inspections can detect potential problems.

The maintenance and lubrication procedures

specified in this schedule must be performed by

a Braun authorized service representative at the

scheduled intervals according to the number of

cycles.

The Vangater II is equipped with hardened pins

and self-lubricating bushings to decrease wear,

provide smooth operation and extend the service

life of the lift.

When servicing the lift at the recommended inter-

vals, inspection and lubrication procedures speci-

fied in the previous sections should be repeated.

Clean the components and the surrounding area

before applying lubricants. LPS2 General

Purpose Penetrating Oil is recommended where

Light Oil is called out. Use of improper lubricants

can attract dirt or other contaminants which could

result in wear or damage to the components.

Platform components exposed to contaminants

when lowered to the ground may require extra

attention.

Lift components requiring grease are lubricated

during assembly procedures. When these com-

ponents are replaced,

grease must be

applied during instal-

lation procedures.

Specified lubricants

are available from

The Braun Corpora-

tion (part numbers

provided below).

All listed inspection,

lubrication and main-

tenance procedures

should be repeated at

“750 cycle” intervals

following the scheduled “4500 Cycles” maintenance.

These intervals are a general guideline for scheduling

maintenance procedures and will vary according to

lift use and conditions. Lifts exposed to severe condi-

tions (weather, environment, contamination, heavy

usage, etc.) may require inspection and maintenance

procedures to be performed more often than speci-

fied.

Discontinue lift use immediately if maintenance

and lubrication procedures are not properly per-

formed, or if there is any sign of wear, damage or

improper operation. Contact your sales representa-

tive or call The Braun Corporation at 1-800-THE LIFT.

One of our national Product Support representatives

will direct you to an authorized service technician who

will inspect your lift.
