1. Preparations Before Work
1) Inspect the amount of hydraulic oil.
If insufficient, fill the oil tank with enough hydraulic oil.
2) Check that the stop valve is opened.
3) Operate after checking that all bolts and nuts are tightened properly.
If bolts or nuts are loosened, serious issues such as leaking of oil, falling of bolts and
damaging of screw threads can occur.
4) Surely push grease into the pin and bush before use.
5) Operate the product smoothly, always check for abnormalities, and pay attention to leaking
of oil.
2. Installation of Wood Grapple
1) Put rectangular lumber on a flat ground surface and place the product on top.
2) Close the stop valve of the excavator and adjust setting pressure of the cylinder line and
motor line. (Refer to setting pressure of the product.)
When adjusting setting pressure, consult with A/S personnel or employee of our company
for advisory.
3) After aligning the hole on the excavator arm with the hole on the attachment bracket, insert
two bracket pins and tighten the stop ring, bolts and nuts.
When attaching, use hand signals to make sure that the product bush is properly aligned
with the hole on the excavator arm.
4) Open the union cap of the stop valve and connect the product hose.
Since oil residues can flow out of the pipe, prepare an empty box to receive flowing oil.
