equipment operator manual. Clear the area of bystanders, especially small children, when performing any maintenance or adjustments. Keep
work area clean & dry. Use adequate lighting for the job. Use only tools, jacks & hoists of sufficient capacity for the job. Never lubricate,
service, or adjust machine while it is moving. Keep hands, feet, & clothing from power-driven moving & rotating parts. Disengage all power &
operate controls to relieve pressure. Lower equipment to the ground and stop the engine. Remove the key. Wait for all moving parts to stop
