OPERATION
PREOPERATION PROCEDURES
CHECK THE POWER SOURCE
1.Using a calibrated flow meter and pressure gauge, make sure the hydraulic power source develops a flow of
2.Make certain that the power source is equipped with a relief valve set to open at
3.Make certain that the power source return pressure does not exceed 250 psi/17 bar.
CONNECT HYDRAULIC HOSES
1.Wipe all hose couplers with a clean
2.Connect the hoses from the hydraulic power source to the chain saw fittings or quick disconnects. It is a good practice to connect return hoses first 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 flow is in the proper direction. The female cou- pler on the chain saw is the inlet (pressure) coupler.
4.Move the hydraulic circuit control valve to the “ON” position to operate the chain saw.
NOTE:
If uncoupled hoses are left in the sun, pressure in- crease inside the hoses might make them difficult 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 DS11 to a city or auxiliary water supply.
2.Holding the saw away from your body, turn the saw on and read the water pressure at the water gauge. Water pressure must be at least 35 psi/2.4 bar to avoid damage to the saw bar and chain.
3.If you plan on operating the chain saw in freezing weather, make sure you purge all the water from the system after each use.
4.If the water pressure is below 35 psi/2.4 bar, make the required adjustments to the water supply. If the required pressure cannot be achieved, you must use the Stanley Electric Water Pump Kit (Part Number 26020 or the Power Unit Water Pump Kit P/N 29361).
CHECK CHAIN AND BAR ADJUSTMENT
1.Check the chain tension often during operation, es- pecially during the first 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.
2.Make sure the chain does not exceed a clearance of 1/4 in./6 mm from the bar (see Figure 2). Exceeding the maximum clearance increases the chance of the chain being dislodged from the bar groove.
Min 1/16”

3.Make sure the bar attaching nuts are fully tightened and the chain guard is in place.
CHECK CHAIN SEGMENT WEAR
1.Using adjustable calipers, measure several chain segments as illustrated in Figure 3.

2.If the average measurement is less than 1/16- inch/1.6 mm, then the chain must be replaced. Refer to your Service Manual for chain replacement pro- cedures.
CHECK THE WATER SUPPLY
IMPORTANT
Chain and bar damage will occur if the chain saw
operates without the proper water supply.
1.Always have water running before starting the chain saw.
2.Water flow must be 4 gpm/15 lpm at 50 psi/3.5 bar minimum.
