■Setting up a post
Anchor bolt installation
① Drill a hole
② Clean the inside of the hole
③ Put an anchor bolt into the hole and hammer
it until it reaches the bottom of the hole
④ Tighten the bolt with a spanner (ⓐ:35~45mm)
(Tighten more 80N.m~100N.m)
▶Before securing with anchor bolts, ensure
that the post is vertical in both directions.
Vertical balance
Check that the post is vertical in both
directions and adjust by means of the shim
plates provided.
Fix by anchor bolts.

■Connection of the hydraulic hose
▶Before setting up the post, connect the
hydraulic hose and tighten it with a 19/17mm
spanner. Check for oil leakage.
Installation

■Cable synchronization
▶The cables ensure synchronization
between the carriage on the power post and
the carriage on the slave post.
① Top roller for cable.
② Synchronization cable from the
opposite carriage.
③ Synchronization cable mounting
bracket.
④ Bottom roller for cable.
Check which carriage first touches the
base plate of the post when the hoist descends
and then tighten. This cable until both carriages
lest on lie base plates simultaneously.
Adjusting the cables
How to check the tuning
adjustment.
① Check with "naked eyes" that the bottom
post reached simultaneously see above.
② Check with ears
Check the sound of the parking pawls
engaging in each slat during ascent.
The "clicks" should be simultaneously
if not tighten the cable on the later pawl.
(The wire of the locker that sounds later
shall be tightened more tensely.)

Operation
Check that the carriages and arms are at
lowest position by operating the lock
release lever and descend lever.
Prior to use
1
At the bottom position the arm locks
are released. Swing the arms to the
straightahead position as shown.
Prior to vehicle entry
2
Position the vehicle centrally between
posts with the vehicle's center of gravity in
line with the 2 posts.
Vehicle entry
3
Raise the hoist approx. 50mm and
check visually and mechanically to
ensure that each arm lock is firmly
engaged.
Check the arm locks
5
Swing in the 4 arms under the vehicle and adjust
the length of each arm so that the pick-up pad is
directly underneath the pick-point recommended
by the vehicle manufacturer. Each pad is fitted with
telescopic thread allowing a 2-stage adjustment.
Adjust the height of each pad to engage the pick-up
point.

After checking that the 4 pads are correctly adjusted
under the pick-up points recommended by the
vehicle manufacturer and that the arm locks are
engaged as previously described, press the
ascent push button and raise the hoist to the
required working height.
Ascent

Before going under the hoist, check again visually
the pick-up pads and arm locks. After repair of the
vehicle, check the floor and work area to ensure that
there are no obstructions. Press the descent push
button to lower the hoist. When the hoist is at the
bottom position, the arm locks are released
automatically. Release the pick-up pads from the
pick-up points by screwing down the telescopic
threads. Swing the arms from under the vehicle to

Operation Procedures of Each Part
■ Arm Lock Operation
When the carriages go up the arm locks
are engaged automatically. Ensure that the
gears controlling the locks are in mesh,
i.e. fully engaged. If not, the arm must be
marginally adjusted until the spring loading
operates and locks successfully.
Ascent

■ Arm Operation
the arms are telescopic with either 2
sections or 3 sections as shown to allow
the required adjustment.

Maintenance
■ Lubrication
■ Cleanliness
▶At 2-or 3-month intervals, depending on
service usage.
▶Apply molybdenum disulphide grease liberally to
the carriage guides and the guide runners inside
the posts.

▶Check every day that the hoist is clean and
that the work area is clean and free from
debris or obstructions.
▶Clean safety devices at 2-or-3-month intervals,
depending on service usage.
- Clean the arm lock gears and surroundings,
lubricate the gear teeth and the release
mechanisms. Clean the safety lock pawls, and
lubricate the axles.
■ Synchronization Cable Adjustment
▶Check that both carriages are fully parked on the
base of the hoist at the bottom position. Raise the
hoist without load and listen to the audible clicks of the 2
lock pawls. The synchronization of the
2 carriages is correct when both lock pawls click
simultaneously. Adjust the length of the 2 cables as
shown to fulfill this.
▶Lubricate with oil the upper and lower cable
rollers and axles.
