Melnor XT4100 Manual

ATTENTION
Read this first.
If the sprinkler stops working due to debris/dirt (poor water quality),
please remove it from the hose-end and the cleaning tool ( a pin )
located in the end of oscillator, then connect to a tap (faucet) with
water running, spin the tube gently back and forth for few minutes.
Screw the tool firmly back into place. The sprinkler should work
normally now.
