directions for use Operation
1) Before start :	check whether air volume is sufficient
2) Loading :	- check whether air volume is sufficient. - Check whether the scale shows between 0.2kgf and 0.7kgf. - Overload (overload may cause serious problems on our product, which is not liable for the company)
3) Unload :	- drive with tri-axle uplifted. - Driving with tri-axle lowered may cause loss of driving force.
4) Parking on slope : lower the tri-axle (preventing slipping)
5) Driving on rainy road or snowy road
- Drive with tri-axle uplifted if possible. - The rear part of a vehicle may turn left or right as the tri-axle is first put on the brake when a truck sets suddenly break.
6) Driving on unpaved road : lower the tri-axle and adjust air volume as less as possible(1.5kgf on gauge) before driving.
7) Applying axle and kit grease
- Applying grease every 3-month. - Replace a rubber bushing if the clearance is widened. - It may cause damaged parts or shortened life unless grease is replenished or replaced properly.
8) Effective driving tips
- Driving on load with the gauge set between 0.1 and 0.3 kgf may reduce tire wear and increase braking power.
9) Gauge scale and weight
Air pressure(BAR) Weight(loadage) A special vehicle should consider the vehicle’s weight together Load state 1.5 ~ 2.0±0.5 8 ~ 12 tons ※ means an approximate value ※ It may be different depending on the location of load. 2.5 ~ 3.0±0.5 13 ~ 15 tons 3.5 ~ 4.5±0.5 16 ~ 20 tons 5.0 ~ 6.5±0.5 21 tons and more
※ Precautions ※ - It must be checked in a month as it differs depending on vehicle types. - Durability may suffer from faults if driving it after setting the tri-axle on over-pressure(5kg and more). - When turning suddenly or loading/unloading, please drive with the tri-axle uplifted as possible.
10) U bolt and other bolts are factory-set as the preferable torques when released.
Make sure to regularly re-tightened them as follows. ① 5 days after release or after repairs.      ② 30 days after release or repaires. ③ 60 days after release or after repairs.    ④ every 6-month.
11) Regular maintenance tips
Checklist Replacement intervals Remarks Checking/replacing airbag(frequently) ◇ RIDE BAG ◇ LIFT BAG - the interval may be shortened in case of excessive driving (distance) Checking Axle (2,000km/month) ◇ Checking hub bearing - thoroughly check bearing state - Applying grease into every point - Adjusting lining - Checking wheel nut tightening torque - Checking U bolt tightening torque Checking tires (2,000km/month) ◇ Tire balance - checking tire wear and balance Kit structure (2,000km/month) ◇ checking any crack or bolt tightening - no crack should exist - Check bushing wear - Check every coupling torques - Check spring damper diminution reduction(large vehicle) - Check air leak of air-pressure parts
12) Troubles and troubleshooting
Troubles Cause Measure Pusher axle Up, Down Malfunction ◇ Impurities are inserted into valves, causing malfunction ◇ when wire disconnected Commonness ① Regularly moisture emitting in air tank(drain cock) ② Replace an air drier filter Down(lowering) defect ① Turn it on and check air on main gauge is enough ② Leave the switch with tri-axle lowered(ON state) ③ Check a fuse in the fuse box(checking a relay in the fuse box) Up(raising) defect ① Check air on main gauge is enough (axle does not move up in case of insufficient air volume) Destructed airbag ◇ Worn airbag (connection between rubber and plate) ◇ Side scratch of airbag - replace the airbag One-sided (uneven) wear ◇ Brake lining’s one-sided(uneven) wear - replace the lining - Adjust left/right lining intervals
