WARNING:
BE CAREFUL WHEN YOU MOVE THE ENGINE STARTER. BECAUSE THE STARTER WEIGHS APPROXIMATELY 38 POUNDS (17 KG), INJURY CAN OCCUR.
WARNING:
USE PERSONAL PROTECTION EQUIPMENT. USE THE ENGINE OIL IN A WELL-VENTILATED AREA. ENGINE OIL IS TOXIC.
CAUTION:
DURING INSTALLATION, KEEP THE STARTER PERPENDICULAR TO THE AGB MOUNTING PAD TO PREVENT SEIZE AND/OR DAMAGE TO THE OUTPUT DRIVE SHAFT.
CAUTION:
DO NOT INSTALL THE STARTER ON THE AGB WITHOUT ITS SEALING ITEMS (NEW O-RING AND THE RE-USED OR NEW SEAL RING). IF THE STARTER IS INSTALLED WITHOUT THESE SEALS, THE ENGINE CAN LEAK OIL. THIS CAN CAUSE ENGINE FAILURE.
CAUTION:
DURING INSTALLATION, ADJUST THE ORIENTATION OF THE LOWER DUCT. MAKE SURE THAT THE PS3 LINE DOES NOT TOUCH THE LOWER DUCT OR OTHER PARTS IN THIS AREA. IF IT DOES, CHAFING OF THE PS3 HOSE CAN OCCUR.
