SAFETY INSTRUCTIONS 

WORK SAFELY – A CAREFUL OPERATOR IS THE BEST INSURANCE AGAINST ACCIDENTS!!

 

 

 

WARNING SECTION [Continued] 

 

 

 
 
 
 
 
 

 

Hydraulic fluid under pressure can penetrate the skin 
and cause serious injury or death. Hydraulic leaks 

under pressure may not be visible! 

 

If any fluid penetrates the skin, GET IMMEDIATE 
MEDICAL ATTENTION!! 

 

Wear safety glasses, protective clothing and use a 
sound piece of cardboard or wood when searching for 
hydraulic leaks. DO NOT USE YOUR HANDS! 

 

Before connecting or disconnecting hydraulic hoses, 
read your tractor or power unit’s operator’s manual for 
detailed instructions on connecting and disconnecting 
hydraulic attachments. 

 

Make certain that all parts meet the specifications for 
this product when installing or replacing hydraulic 

hoses or fittings. 

 

After connecting hydraulic lines: 

  Slowly and carefully raise the loader and cycle the 

rollback / dump cylinders to check hose 
clearances and to check for any interference. 

  Operate the hydraulics on this product to check 

hose clearances and to check for any 
interference. 

  Make certain that the hoses cannot interfere with 

or actuate the quick-attach mechanism. 

  Make certain that hoses will not be pinched, or get 

tangled, in any equipment. 

 

Do not lock the auxiliary hydraulics of your power unit 
in the “ON” position. 

 

Refer to your power unit’s operator’s manual and this 
manual for procedures and intervals, then inspect and 
maintain the entire hydraulic system to insure that the 
fluid remains cleans, that all devices function properly 

and that there are no fluid leaks. 

 

 
            Think SAFETY!    
  
                                Work SAFELY! 

 

 
 
 

 

Refer to the operator’s manuals of your power unit, 
your loader and your quick-attach for special or 
detailed mounting instructions. 

 

This product should fit onto the quick-attach or loader 
arms of your power unit the same as the original 
products that were designed by your loader / quick-

attach manufacturer. 

 

If this product does not fit properly, contact HLA before 
operating. 

 

Never place your finger into the mounting plate or 3-
point hitch or loader holes. A slight movement of the 
power unit or this product could cause serious injury. 

 
 

 

 

Make certain that all safety signs are in place and 
legible. Refer to the safety sign page in this manual for 
the placement of safety signs for this product. 

 

Replace all damaged or excessively worn parts and 
hardware only with genuine HLA parts or with properly 
rated fasteners, hydraulic hoses or fittings. 

 

Make certain that all locking pins, latches and 
connection devices are properly installed and secured. 

 

Make certain that all protective guards, canopies, 

doors, etc. are in place and secure. 

 
 

 

 

Never use Broom on a power unit that is not equipped 
with a cab or ROPS, and operator restraints (seat belts 

or equivalent devices). 

 

Know your loader’s safe operating weight limit and the 
weight of your loader attachment. 

 
 
 

 

Make no modifications to your Broom 

 

Always wear heavy leather gloves when working on 
the Broom since wires in the brush could puncture or 
scratch exposed skin. 

 

When making repairs, use only genuine HLA parts or, 
for fasteners, hydraulic hoses or hydraulic fittings, use 

only properly rated parts. 

 

Replacement parts, for parts with safety signs 
attached, must also have safety sign attached.
