MACHINE - OVERALL CHECK
Shields and Guards - Check that all shields and guards are installed and securely fastened to the machine.
Replace or repair any shields or guards that are damaged or have missing parts.
Hardware - Check machine for loose, worn, or missing parts and hardware. Tighten any loose parts and
replace any worn or missing parts. Refer to the Parts Manual for replacement parts.
Frame - Check frame and contact dealer immediately if you notice any bends, cracks, or breaks.

HYDRAULIC SYSTEM - CHECK

WARNING: Pressurized fluid can penetrate body tissue and result in serious injury or
death. Leaks can be invisible. Keep away from any suspected leak. Relieve pressure in the
hydraulic system before searching for leaks, disconnecting hoses, or performing any other
work on the system. If you must pressurize the system to find a suspected leak, use an
object such as a piece of wood or cardboard rather than your hands. When loosening a
fitting where some residual pressure may exist, slowly loosen the fitting until oil begins to
leak. Wait for leaking to stop before disconnecting the fitting. Fluid injected under the skin
must be removed immediately by a surgeon familiar with this type of injury.

• Ensure all connections are tight and hoses are in good condition before applying hydraulic pressure to the
system.
• Check for leaking hoses, kinked hoses, and for hoses that rub against each other or other parts of the
machine. Replace all deteriorated or damaged hoses. When a hose with a protective sleeve is replaced,
always install a new protective sleeve over the new hose.
• Check hydraulic cylinders for leaks and damage. Repair or replace as required.

Step 5: Tighten chain. Refer to “Digging Chain - Adjust,” page 60-6.

DIGGING CHAIN WEAR - CHECK

As the digging chain is used, it will stretch. This is caused by wear at
all of the chain pivot points.
The digging chain is worn out when it has stretched 6% or more from
its original length.
To check amount of stretch, count eleven pins. On a new RT200
digging chain, the measurement (1) from the center of the first pin to the center of the eleventh pin is 16.5˝ (42
cm). If the measurement exceeds 17.5˝ (44.5 cm), the chain is worn out.
As the digging chain wears, adjust boom length to maintain proper chain tension. Refer to “Digging Chain -
Adjust,” page 60-6. When the boom cannot be extended farther to compensate for chain wear, remove two chain
links as directed in following procedure, retract boom and reinstall chain.

2
IMPORTANT: Do not use a cutting torch. A cutting torch may fuse the pin to the 1
chain's sidebar or alter the strength of the sidebar steel.
Step 4: Drive pin out of the digging chain.
NOTE: Because the holes in the chain sidebar are not the same size, the pin can only be driven out of the digging
chain from the pin side (1).

CUTTERS - REPLACE
The cutting teeth are cup cutters, shark teeth, or rotary bits.
Keep cutters tight. Check cutting teeth regularly for wear. Broken, missing, or badly worn teeth should be
replaced immediately to avoid loss of engine power, slowed trenching speed, excessive wear on chain link heels,
or machine pulling toward one side.
The cup cutters have hard surfacing applied to the main wearing surface. Cup cutters are recommended for
digging in sand, dirt, and clay.
Rotary bits are carbide-tipped for hard and dry or rocky conditions. Productivity is significantly reduced if using
rotary bits in wet or sticky digging conditions.
