General Safety WARNINGS!

When using this electric sca dethatcher, basic safety 

precautions should always be followed to reduce the risk of 

fire, electric shock and personal injury. 
Before using the sca dethatcher, take the time to 

familiarize yourself with the controls, especially how to stop 

the machine in an emergency. The only individuals who should 

use the sca dethatcher are those who have a thorough 

understanding of the instructions and who know how to 
operate the machine. Children should never be allowed access 

to the sca dethatcher.

Retain this manual for future reference and reread it at the start 
of each dethatching session.

General Safety

1.  Keep work area clean and well-lit – 

Cluttered, dark 

areas invite accidents. 

2.  Replacement parts – 

When servicing this unit, use only 

identical replacement parts. Replace or repair damaged 
cords immediately.

3.  Keep children, bystanders, and pets away –

 All 

spectators, including pets, should be kept a safe distance 

away from the work area.

4.  Dress properly –

 Do not wear loose clothing or jewelry 

as such articles can get caught in moving parts. Wear a 
protective covering to contain long hair. Wearing rubber 
gloves and substantial non-slip footwear is recommended 
when working outdoors.  

5.  Avoid accidental starting –

 Do not carry the sca 

dethatcher with your finger on the switch. Make sure the 

switch is off before plugging in the unit.

6.  Do not force the tool –

 It will perform better with less 

likelihood of personal or mechanical injury if it is used at 
the rate for which it is designed.

7.  Wear personal protective equipment – 

When using this 

tool, wear safety glasses with side shields or goggles to 

provide necessary eye protection. Wear ear defenders to 
prevent hearing damage. Use a face or dust mask if the 
work environment is dusty.

8.  Disconnect the tool – 

Disconnect the sca 

dethatcher from the power supply when it is not in use, 

before servicing it, when changing accessories, and when 

performing any other maintenance task.

9.  Store idle tool indoors – 

When not in use, the sca 

dethatcher should be stored indoors in a dry and high or 
locked-up place out of the reach of children.

10.  Maintain the 

sca dethatcher

 with care – 

Keep 

cutting edges sharp and clean for optimal and safest 
performance.

 

Inspect the sca dethatcher cord periodically and 

if damage is found have it repaired by an authorized 
service facility. Extension cords should also be inspected 
periodically and immediately replaced if damaged. Keep 

handles dry, clean and free from oil and grease.

11.  Use the right tool – 

Do not use the tool for any job except 

that for which it is intended.

12.  Avoid dangerous environments – 

Do not use the 

sca dethatcher in rain, damp, or wet locations. 

13.  Stay alert – 

Watch what you are doing. Use common 

sense. Do not operate the 

sca dethatcher 

when you 

are tired or under the influence of drugs, alcohol,

 or other 

medication.

14.  Do not overreach – 

Keep proper footing and balance at 

all times.

15.  Check Damaged Parts – 

Before further use of the 

appliance, a guard or other part that is damaged should 

be carefully checked to determine that it will operate 
properly and perform its intended function. Check for 

alignment of moving parts, binding of moving parts, 

breakage of parts, mounting, and any other condition 

that may affect its operation. A guard or other part that 

is damaged should be properly repaired or replaced.
