Unscrew the handgrip until it bumps to nut. Press trigger of gun several times in order to control the working and switching pressure. If necessary, repeat phase 2.5. Turn handgrip back until minimum/steam pressure stage is obtained (according to indication of manufacturer). Mount fixing nut until swing of grip. Fixing nut (A) defines the stage of low and steam pressure, nut (B) defines the stage of working and switching pressure.1. Loose fixing nut (A) and take off handgrip. Also loose nut (B) and nut (C). Put handgrip back in position without fixing it. Switch on high pressure device and press gun trigger.2. While keeping an eye on the gauge`s pressure slowly tighten the handgrip. When working pressure is attained turn handgrip one rotation tighter. In this position nut (B) must be next to the handgrip. Otherwise, nut (B) has to be adjusted until this position is reached.Setting up of a regulation valveST-280 = inlet 3/8\ = outlet 3/8\ = bypass 1/4\ = pressure gauge 1/4\Max. 250 bar / 80 %u00b0CType A Type C Type DR+M Nr.200 280 510 30 l/minST-280 R+M Nr.200 280 526R+M Nr.200 280 646R+M Nr.200 280 650Symbols flow inlet outlet bypass pressure gaugewww.rm-suttner.comR+M Nr.200 291 500 40 l/minR+M Nr.200 291 550 40 l/minST-291 ST-291 with switch Repair kits ST-291 = inlet 3/8\= outlet 3/8\= bypass 1/2\ = inlet 3/8\= outlet 3/8\= bypass 1/2\and cable 1,200 mm.
