● The function of auto-off for saving power; the device

will turn itself off without any operation in five minutes;

● On screen shows LOW signal when power is low,

and shut it down automatically.

7.4 Auto-off

9.Maintenance

● Clean the conduit and the impact body of the impact

device with nylon brush after utilization 1000~2000

times. First screw the back-up ring off, pick the impact

body out, screw nylon brush inside conduit

counterclockwise till the end, then pull it out. Repeat 5

times, then put the impact body and back-up ring on;

● Release the impact body after using;

● All kinds of lubricant are not allowed inside the impact

device.

● Testing the standard Rockwell hardness block, all errors

are more than 2HRC, the possible reason is the

wear-out-failure of the head, changing it or the impact

body should be considered;

● When the tester appears other abnormal phenomenon,

please do not remove or adjust any fixed assembly

parts. Please fill out the warranty card and submit it to

our maintenance department to implement the warranty

regulations.

● The product is powered by 3.7V 350mAh lithium

battery, which is not removable. When the product

cannot be turned on or the power display is blank,

please charge it in time. Please use the DC 5V 0.5A

charging adapter to charge the product, and the

charging interface is Type-C.

● When charging, battery symbol scrolls through. When

fully charged, the battery symbol is displayed as full

battery .

● Store it in normal temperature and far away vibration,

strong magnetic field,corrosive medium, humidity and

dust;

● Transport it with original package in three-class

highway.

the range of impact device application:

DC-type for hole or inner cylindrical surface;

DL-type for spindly narrow groove or hole;

D-type for regular testing;

D+15 for groove or sunken surface due to its smaller contact area and lengthening;

C-type for hardened layer and samples with minor diameter and thinner wall due to

its smaller impact force which usually cause damage on surface;

G-type for larger thickness and more rough casting samples;

E-type for highest hardness materials.
