SAFETY
PERFORMING MAINTENANCE:
Carefully review, understand, and follow the “maintenance” section in this owners manual before
attempting to service backhoe. Observe proper maintenance schedules and repairs to keep unit in
safe working order. See on page 15.
Lower the bucket or attachment to the ground, shut off tractor engine, and relieve pressure in the
hydraulic system before adjusting, lubricating, or servicing the backhoe.
Escaping hydraulic oil under pressure can penetrate the skin. Never use any part of your body to
check for hydraulic leaks. Use cardboard when checking for leaks. See Fig. 5-1. Relieve hydrau-
lic pressure before disconnecting any hydraulic line. Failure to heed may result in serious injury or
death.
Before disconnecting hydraulic lines, lower the backhoe and attachments. Lock out the hydraulic
supply and relieve all hydraulic pressure.
Replace any damaged or painted-over decals. See Page 6 for replacement decals.
REMEMBER:
1. Move Slowly!
2. Always use care and common sense!
3. Be careful for your own sake and for that of others!
4. Koyker Mfg. Co. includes all reasonable means for accident prevention except a safe and
careful operator.
