Graco SDM5 User Manual

1.

a. Thread new nozzle (33) onto extension (20). 
b. With an open-end adjustable wrench on flats of 

nozzle bushing, tighten firmly.

2. Open automatic twist lock nozzle and all fluid 

shut-off valves. Start pump to pressurize system. 
See Operation Screens, Dispensing in either the 
Manual or Preset Mode instructions beginning on 
page 21 for complete meter operation information.

3. To ensure dispensing accuracy, purge all air from 

the fluid lines and dispense valve before you use it. 

4. Set the system flow to the desired flow rate. 

•

Only tighten nozzle with wrench on flats of the 
nozzle bushing. 

•

Do not disassemble the bushing from 
nozzle. Disassembly will affect performance of 
the nozzle.

Do not trigger meter when nozzle is closed. Fluid 
will build up behind the nozzle, leak from the nozzle, 
and unexpectedly be expelled when the nozzle is 
opened. If you do accidentally trigger the meter with 
the nozzle closed, point the nozzle into a waste 
bucket and open the nozzle to relieve pressure and 
expel the built up fluid.
