7. Put disassembled parts in order so that parts such
as bolts are not left behind in the machine. And
check that no parts run short at assembly.
8. Watch your step in the following cases:
When stepping up to or stepping down from the
upper surface of a boom for replacing wire ropes
and applying grease. Be careful not to stumble
on protrusions on the upper surface of a boom.
When greasing at the root of a elevating cylinder
When checking engine oil, radiator coolant, or
battery fluid.
When replacing a filter of air cleaner
When getting on and off the cab
Be careful not to slip in the above operations in
winter as snow and ice may attach to the exterior
of boom and it becomes very slippery.
2.2 Dismounting & disassembling
1. Before dismounting and disassembling, make sure
of the construction and part sales unit by reading
this manual and the separate parts catalog, then
understand the procedures of dismounting &
remounting and disassembling & reassembling.
2. When dismounting piping or equipment that may
contain pressurized oil or air, be extremely
cautious and dismount them only after discharging
the confined pressure.
3. Before removing, clean the part to be dismounted
and the area surround it. Seal the opening with a
plug or tape, etc. to prevent foreign material from
entering it.
4. Measure and record the data such as shim
thickness adjustment and pre-load at disassembly
that will be required at reassembly.
5. If required, before disassembling clearly put marks
to avoid errors at reassembling.
6. If a part cannot be removed after removing bolts or
nuts fixing it, don't apply too much force to it but
check the part for the cause. Only after relieving
the cause, proceed disassembling.
7. Use lifting slings appropriate for the weight and
characteristics of a part. Lift up it in balanced
condition.
In case that the position of the center of gravity is
not clear and there is a possibility of swing of load
after removing, use two hoists.
8. If a part cannot be lifted smoothly, make sure that
all the fasteners are removed and other parts don't
hinder removing.
2.3 Remounting & assembling
1. Before assembling, clean all the parts and repair
or replace defective parts.
2. As dirt and soil adversely affect sliding portions
and they may decrease the life of the machine,
pay special attention to avoid intrusion of dirt and
soil.
3. Use special tools for parts when specified to do so.
4. Remove dirt, soil, water, and resin completely from
surfaces where liquid gasket will be applied.
5. After remounting, be sure to inspect the machine
and verify that there is no error by oversight. If
adjustment or air bleeding is required, conduct it
according to instructions. Conduct function and
performance test to verify its integrity.
3. Cautions in operation
3.1 Brake fluid replenishment
1. When the brake-warning lamp (for fluid level) is
lighted, replenish brake fluid and check and make
sure of the thickness of disk brake pads. (Refer
to Chapter Y for periodical inspection periods.)
2. Check the thickness of disk brake pads whenever
brake fluid is replenished.
3.2 Handling of battery
1. Erroneous handling of a battery may cause it to
catch fire and explode.
Be extremely sure to avoid short circuits, sparks
and fire of cigarettes and the like when using a
jumper cable. They are very dangerous.
Charge up batteries and use them only in well
ventilated places.
