BChecking of intake air line
[V2607-CR-TIE4, V3307-CR-TIE4, V3800-TIE4]
Visually check for cracks, gas leak and anything else
unusual.
Check to see if the lock bolts and nuts are tight enough.
In particular, the hose between the turbo-charger and the
intake manifold must be checked for cracks and come-off.
This is because this line will be under high pressure.
See if this hose is deep enough into the pipe. If not,
reinsert the hose deeper. Put the clamp on the hose free
of the bulge of the pipe, and tighten the clamp bolt to the
specified torque.

local regulations.
A Do not drain oil after running the
engine. Allow engine to cool down
sufficiently.

every 400 hours thereafter. When the annual
operating hours are below 400, replace the oil every
year.
2. Remove the drain plug at the bottom of the engine,

burns.
1. Replace the oil filter cartridge. Oil filter cartridge
should be replaced after the initial 50 hours of
operation and every 400 hours thereafter.
2. Remove the old oil filter cartridge with a filter wrench.
3. Apply a film of oil to the gasket for the new cartridge.

5. After the new cartridge has been replaced, the engine
oil level normally decreases a little. Thus, run the
engine for a while and check for oil leaks through the
seal before checking the engine oil level. Add oil if
necessary.
A Wipe off any oil sticking to the machine completely.
