Handling high pressure hoses

• Kinks and cracks on high pressure hoses could cause breakage. Do not use any hoses with kinks and cracks.

• If fuel hoses or hydraulic oil hoses are loose or cracked, they could cause fire. Always repair them immediately.

Parts that have been removed

• Place removed parts in a stable condition; otherwise, they may fall down and become dangerous. • Keep children and bystanders away from the parts storage area. • When the ground is not hard and solid, parts may sink or fall down from their own weight. Arrange the parts storage area in a place which has level and hard ground. • If soil or dirt gets inside pipes, it could cause malfunction or errors. Plug or cap pipes of removed parts.
