It's a handle scalers which is powered by air, used in removing scales and surface Paint from the ship deck. The scaler has a handle, allowing the operator to stand during use, relieving fatigue and protecting the eyes from dust and chipped metal or scale.
Check before work:
1.Injet lubricant(46#machine oil)into the oil cylinder(11)to 1/2 or 2/3 of the volume.
Don't inject too much to avoid the overflow.Adequate will be OK.
2.Check whether the air will be supplied favorably.
3.Check the distance between the piston ④28mm(5)and the scale surface.5-8mm will best.Normally,this will be adjusted by the manufacturer before it leave the factory.
Operation principle:
The best work power is 0.6-0.8Mpa.The air tube is φ10mm inside high-pressure tube.Compressed air nozzle can be connected direct to the 1/4'nozzle(13)on it.After the check,turn the ball valve handle(12)to open the straight valve,the air go through the oil cylinder(11),pass the elbow for 1/2'hose,enter the cylinder block(8),then drive the piston(5)(11pcs in all)to attack continuously.At the same time.6mm tube connect to the red p6mm switch.During the work,it will blow off the scale,make the surface clear.When finish the work,turn off the ball valve handle,then cut off the air supply.
Note:
1.Although the piston has been adjusted before it leave the factory.it will has normal wear after a time of work.Please adjust the distance between the piston and the scale surface.Screw of the screw on the board of front wheel assembly,adjust the distance to 5-8mm,screw up the screw,then it can work again.
2.Add the lubricant in time,to make the piston enough flexible,so it can work much longer.
3.Periodic maintenance is needed,and change the damaged parts in time.
