Follow these guidelines before operating any jobsite equipment:
• Complete proper training and read operator’s manual before using equipment.
• Contact your local One-Call (811 in USA) or the One-Call referral number (888-258-0808 in USA and
Canada) to have underground utilities located before digging. Also contact any utilities that do not
participate in the One-Call service.
• Classify jobsite based on its hazards and use correct tools and machinery, safety equipment, and work
methods for jobsite.
• Mark jobsite clearly and keep spectators away.
• Wear personal protective equipment.
• Review jobsite hazards, safety and emergency procedures, and individual responsibilities with all
personnel before work begins. Safety videos are available from your Ditch Witch dealer.
• Replace missing or damaged safety shields and safety signs.
• Use equipment carefully. Stop operation and investigate anything that does not look or feel right.
• Do not operate unit where flammable gas may be present.
