PRE-OPERTION PROCEDURES
CHECK THE POWER SOURCE
1. Using a calibrated ow meter and pressure gauge,
make sure the hydraulic power source develops a
ow of 7–9 gpm/26–34 lpm for the 8 gpm model and
4–6 gpm/15–23 lpm for the 5 gpm model at 2000
psi/140 bar.
2. Make certain that the power source is equipped with
a relief valve set to open at 2100–2250 psi/145–155
bar.
3. Check that the hydraulic circuit matches the tool for
open-center (OC) or closed-center (CC) operation.
The DS06 is designed for open-center operation
only.
CHECK TOOL
1. Make sure all tool accessories are correctly in-
stalled. Failure to install tool accessories properly
can result in damage to the tool or personal injury.
2. There should be no signs of leaks.
3. The tool should be clean, with all ttings and fasten-
ers tight.
4. Observe the arrow on the couplers to ensure that
the hydraulic oil ow is in the proper direction. The
female coupler is the inlet (pressure) coupler.
5. Check that the trigger operates smoothly and is free
to travel between the ON and OFF positions.
6. Check that the chain is properly installed. The chain
is designed to only operate in one direction. Make
sure the chain is installed so the bumper guard pre-
cedes each diamond segment. See Figure 2.

CONNECT HYDRAULIC HOSES
1. Wipe all hose couplers with a clean lint-free cloth
before making connections. If necessary, use a
light-weight penetrating oil in a spray can to clean
the hose couplers before each connection.
2. Connect the hoses from the hydraulic power source
to the chain saw ttings or quick disconnects. It is a
good practice to connect return hose rst and dis-
connect them last to minimize or avoid trapped pres-
sure within the chain saw.
3. Observe the arrow on the couplers to ensure that
the ow is in the proper direction. The female cou-
pler on the chain saw is the inlet (pressure) coupler.
NOTE:
If uncoupled hoses are left in the sun, pressure in-
crease inside the hoses might make them difcult to
connect. Whenever possible, connect the free ends
of the hoses together.
CONNECTING TO A WATER SUPPLY
1. Using a standard garden hose, connect the DS06 to
a city or auxiliary water supply. Make sure the ow is
at least 4 gpm/15 lpm at 50 psi/3.5 bar.
2.
IMPORTANT
Chain and bar damage will occur if the tool operates
without the proper water supply and water pressure.
Make sure the water is running before starting the
tool.
3. If a water pump is being used, refer to the manu-
facturers instructions for use of the pump. Make
sure the pump produces a minimum water ow of 4
gpm/15 lpm at 50 psi/3.5 bar and the water pressure
does not exceed 160 psi/11 bar.
CHECK CHAIN AND BAR ADJUSTMENT
NOTE:
Check the chain tension often during operation, es-
pecially during the rst 1/2 hour when using a new
chain. Adjust the chain accordingly when it becomes
loose. Follow the procedures contained in the Main-
tenance and Adjustments section of this manual.
1. Make sure the chain does not exceed a clearance of
5/16 in./8 mm from the bar (see Figure 3). Exceed-
